Several users on DELL forum confirm the bug on E521 and C521 systems with many major distros (260 bytes, text/html)
2006-10-27 17:31 UTC, John Minter

Description Nacho de los R 2006-10-22 02:03:33 UTC
Most recent kernel where this bug did not occur:2.6.14
Distribution:Ubuntu Dapper, Ubuntu Edgy, SUSE 10.1
Hardware Environment: Dell Dimension E521, nVidia nForce 430 chipset, AMD64 X2,
various USB mice.
Software Environment:
Distribution and mainline kernels above 2.16.14. Compiled for i386 and K7, with
and without SMP.
Problem Description: The USB mouse pointer freezes, while using it, after a
while. The keyboard keeps working, screen output is unaffected. Happens in X,
but also in a text console when running gpm. Unplugging the mouse, then plugging
it back regains control of the pointer, but only for a while.

Steps to reproduce:

load gpm -m /dev/psaux -t imps2 in a TTY
move around for a while
the pointer eventually freezes
start Gnome
use it for a while
the pointer eventually freezes
unplug and replug the mouse
the pointer works again

DMSG Output:
The freezing of the pointer is not detected
Unplugging and replugging is detected
Upon replugging, a new USB device is added, with a higher number than before.


I have a cabled USB mouse AND a wireles USB/mouse combo. The combo mouse was
frozen. The wired mouse freezes. I unplug and replug the wired mouse, and these
lines are added to dmesg output:

[17227523.580000] usb 1-7: USB disconnect, address 15
[17227527.904000] ohci_hcd 0000:00:0b.0: IRQ INTR_SF lossage
[17227528.336000] usb 1-8: new low speed USB device using ohci_hcd and address 16
[17227528.564000] input: Logitech USB Mouse as /class/input/input19
[17227528.564000] input: USB HID v1.10 Mouse [Logitech USB Mouse] on

The wired mouse works again. After a while, it freezes, so I now choose to
unplug the wireless combo:

[17229037.284000] usb 1-5: USB disconnect, address 8
[17229041.612000] ohci_hcd 0000:00:0b.0: IRQ INTR_SF lossage
[17229041.916000] usb 1-5: new full speed USB device using ohci_hcd and address 17

[17229042.156000] input,hiddev96: USB HID v1.11 Mouse [Logitech USB Receiver] on

Now I can move the pointer again with the wireless mouse, but not with the wired
unit. Let's unplug/replug the wired mouse too; these lines are added

[17229621.532000] usb 1-8: USB disconnect, address 16
[17229625.532000] ohci_hcd 0000:00:0b.0: IRQ INTR_SF lossage

Comment 2 Nacho de los R 2006-10-30 07:50:13 UTC
Ubuntu Edgy with its kernel 2.6.17 boots up with the mouse pointer AND KEYBOARD
already frozen, and unplugging/replugging does not free them. However, if the
mouse and keyboard are plugged into a hub, instead of directly into the PC, then
they work OK when the system boots.

I have not had the chance to test this but for a very short period of time, so I
cannot say that they won't lock later on, but I'll test more and then report my

If anybody listening would like me to do any concrete tests and post any
concrete results, please, ask me.
Comment 3 Nacho de los R 2006-10-31 05:53:58 UTC
I have given it more testing, and as far as I've seen, both 2.6.15 and 2.6.17
work OK when the mouse and keyboard are plugged into a USB hub.
Comment 4 Walter R. Moore 2006-10-31 16:24:31 UTC
Plugging kbd and mouse into a hub did not work for me with 2.6.16 or with (from
the SuSE 10.2 beta) Linux knossos #1 SMP Fri Oct 20 12:25:45
UTC 2006 i686 athlon i386 GNU/Linux -- if anything the symptoms seemed more
Comment 5 Chris Carlin 2006-11-03 07:54:23 UTC
There are reports (see http://ubuntuforums.org/showthread.php?t=279626 comment
39) that this has to do with the way power is managed, that when the processor
takes a lot of power the USB ports are given less... or something. The poster
indicated that this was managed by the kernel, which seems fishy to me.

Supposedly this is confirmed by plugging the mouse into external, powered USB
hubs. Since they have their own power source the lockups don't occur.
Comment 6 Nacho de los R 2006-11-04 10:16:23 UTC
That is nonsense. Power is definitely not the problem. With just a keyboard and
a mouse plugged in the USB ports (or even with just a receiver from a combo),
the problem happens, and the system does not have to be doing anything intensive
at all -- unless moving the pointer about is too much work for an Athlon X2 to

Also, if there was too little power, how come in the combined wireles
mouse/keyboard the keyboard kept working all the time but the mouse died? And
how come when the keyboard and the mouse were two different USB devices the
keyboard keept working and only the mouse freezed, and then came back to life
after replugging?
Comment 7 Chris Carlin 2006-11-05 07:13:53 UTC
Well yes, *I* would question the power drain theory on the grounds that I would
expect the hardware to handle power levels. But then, I know next to nothing
about the inner workings of USB. For all I know some particular work of the
machine causes it (through software or hardware) to lower power delivered to the
USB bus.

Whatever the reason, though, I have verified the suggested workaround of
operating through a powered USB hub. Others have claimed that unpowered hubs
don't fix the problem, which lends support to the whole power management theory.

But again, I'm not in any way claiming that to be the actual cause. I'm only
repeating a theory suggested elsewhere.
Comment 8 Nacho de los R 2006-11-05 23:43:38 UTC
Maybe I didn't make myself clear: my mouse and keyboard are a Logitech wireless
combo with just ONE device, the receiver, plugged into jus ONE port. There is no
way that power could fail to the mouse but not to the keyboard, but still the
mouse pointer freezes while the keyboard keeps working. And, as you say, if I
plug the receiver into a hub, then there is no mouse lockup.

And If I plug a second mouse when the first one freezes, the second mouse works
perfectly for a while, which would indicate it is receiving enough power. And if
the two mice are plugged in since the beginning, only the one in actual use
freezes, and the other keeps working for a while after the first one has locked up.

If you know nothing about the internal workings of the USB, rest assured that it
provides far more power than enough for one mouse and one keyboard. If you don't
trust me, google for the specs.
Comment 9 Fabio 2006-11-12 17:08:35 UTC
I have the same issue, Dell Dimension C521n with Athlon64 X2 3800+.

Plugging the mouse on a powered USB hub did NOT resolve it for me.  Plugging it
in the from USB slots didn't either.

Sometimes USB my keyboard also locks up / freezes.  But it is less frequent.

Comment 10 Matt Wette 2006-11-12 20:33:52 UTC
I have a C521 from Dell with AMD Athalon X2 3800+ and the nvidia chipset.
I found that if I boot w/o argsI get error messages of "MP-BIOS bug: 8254
 ..." and I get only 1 CPU on-line.  If I boot with "nolapic" I get other
messages and only one CPU on-line.  However, my mouse seems to work reliably.
If I boot with "acpi=off" I get two CPUs but the mouse hangs.  I have been
running Fedora Core 6 with 2.6.18-1.2798.fc6 (i386).  Today I upgraded to
2.6.18-1.2849.fc6 but have not tried with "acpi=off".
Comment 11 Matt Wette 2006-11-13 06:03:56 UTC
This is looking like hardware configuration issue.
Dell released an "urgent" patch for the nVidia SMBus driver.
Also, someone on the Dell forums was able to get a stable
system by recompiling the kernel with Athalon optimizations.

Comment 12 Nacho de los R 2006-11-13 06:08:43 UTC
I compiled a pristine kernel using the config file used by Ubuntu Edgy
2.6.17 kernel; the only option I changed in the config menu was selecting
optimisation for Athlon. There were no nasty surprises during compilation, and
everything worked fine the first time.

I unplugged the USB hub and plugged my wireless mouse/keyboard combo directly
into a USB port and rebooted. My computer booted the new kernel just fine, and
unlike Edgy's 2.6.17, it reached GDM with a fully functional mouse and keyboard,
which was already an improvement on the previous situation (reaching GDM with
BOTH already locked).

I have not given it very extended use, but have used it for about 45 minutes
with no apparent problems, which I don't think I ever could with Dapper's kernel.

What I don't know is what functionality have I given up by not running Ubuntu's
kernel. What patches have they added to 2.6.17 that are absent from

I'll give it more testing and report my findings. If is really solid,
then the problem might be already cured in the kernel, and what would be missing
would be identifying and backporting the changes to whatever previous kernel
version the distributions are using.
Comment 13 Nacho de los R 2006-11-14 00:06:29 UTC has run in my system for a whole day, and I've been actively using it
for about three hours, with no mouse or keyboard lockups.
Comment 14 Peter Pinski 2006-11-17 06:30:32 UTC
With the vanilla kernel compiled myself on FC5 my USB devices freezed,
too. However, they don't with an external powered USB-hub.

Furthermore, my PCI wifi device (D-Link DWL-G520, driver madwifi 0.9.2)
sometimes just lost the connection to the access point without any error message
in dmesg and I couldn't reestablish it until a reboot, after which it worked as
usual until the next freeze. Meanwhile, the onboard ethernet chip (Broadcom
4401) works ok.
Comment 15 Don Richtenburg 2006-11-17 22:10:00 UTC
I have a Dell C521, AMD 64 3200+ (single processor) and have installed SUSE
linux 10.1, X86_64, Kernel
The mouse froze constantly in this distribution as well as Ubuntu and Fedora
6.0. I was going to try a PCI Serial/PS2 card, but have not been able to find
one. As an alternative, I connected a Belkin USB hub (powered) between the
keyboard/mouse and the usb port on the back of the computer. That appears to
have solved the problem for me. I installed the Gnome desktop in Suse 10.1 and
have played lots of games including breakout which is very mouse intensive.
There is no evidence of any mouse problem or keyboard problem with the USB hub
between my mouse and keyboard, and the C521.
The actual hub installed is a Belkin powered hub made for the Mac Mini (Apple)
but I'm sure its electronically the same as any of their current hubs.
This will have to be the bandaid I use until the original problem with the Dell
hardware is solved. (Either through a Bios update, or a Linux kernel fix.
Good luck!

Comment 20 R Kapadia 2006-12-24 12:39:09 UTC
I can confirm this as being an issue across the board on n430 USB, even on HP

Comment 21 Nacho de los R 2007-01-01 12:13:23 UTC
In my experience, kernels and compiled from pristine
kernel.org sources with the default options in the Ubuntu Edgy setup files for
their 2.6.17 don't show the problem at all.

The kernel in OpenSuse 10.2, which is also works
fine for me.

However, Ubuntu's own current compilation for 2.6.20 (available from the Feisty
Fawn repo) also has problems with USB mice locking up, although in this case
unplugging and replugging does not unlock the pointer.

It seems that whatever it is that fixes the problem was added to the incremental
changes to 2.6.18.x, but somehow it is not in 2.6.20.
Comment 22 Luis Felipe Marzagao 2007-01-02 08:07:04 UTC
Hello, there are people reporting that upgrading to Dell BIOS 1.1.4 solves the

Does anyone confirm?!

The file to upgrade the bios is avaiable here:


Comment 23 Matt Wette 2007-01-02 09:54:26 UTC
I have installed BIOS version 1.1.4 on my Dell C521.  It has been
running 2.6.18-1.2868.fc6 i686 "acpi=noirq" for over a day without
mouse freeze.  I was also able to install Ubuntu 6.10; before this
was constantly locking during the install.
Comment 24 Nacho de los R 2007-01-03 05:37:35 UTC
I have updated the BIOS to 1.1.4 in my computer and the problems seem to have
vanished. I have installed Ubuntu 6.10 (it previously locked up during
installation), and have used it for a few hours with no problems.

I did not need to use any ACPI, APIC or LAPIC magic options in the command line.

By the way, both processors come up too (not only one, as before).
Comment 25 Adam Kropelin 2007-01-10 15:52:50 UTC
My E521 has been stable after applying the cited BIOS update.
Comment 26 Luis Felipe Marzagao 2007-01-10 16:59:08 UTC
HELLO, ADAM, what distro are you using?
Comment 27 Chris Carlin 2007-01-11 09:21:51 UTC
FWIW, my e521 running 2.6.18-gentoo-r6 doesn't seem to have benefited from this
BIOS update. I still have only one core and the same USB issues. In fact, the
update seems to have added some annoyances with how it initializes USB devices
and my computer just completely locked up for the first time (coincidence, perhaps).

In short, this BIOS update isn't necessarily the answer...
Comment 28 Walter R. Moore 2007-01-11 09:35:51 UTC
My report.. E521 -- Success with updated BIOS and SuSE 10.1 (original and
updated 2.6.16 kernels). 
Comment 29 Johan Vervloet 2007-01-14 05:38:27 UTC
Bios update fixed the problem, but now my USB hub (which I purchased to work
around the original problem) is not working anymore before the boot procedure
starts.  So in order to use the keyboard for the boot menu or entering setup, I
had to plug it directly into the PC.
Comment 30 Andreas Saebjoernsen 2007-01-27 19:23:48 UTC
I am experiencing that the mouse stop working with my Sony Vaio SZ340 on a
debian etch using kernel and also ubuntu dapper drake.

On this setup the mouse still moves around the screen, but left key clicks has
no apparent effect. The detailed information about my system is:

Comment 31 Isaac Freeman 2007-04-22 19:20:38 UTC
This is odd... My bios says it's version 1.1.5, but the latest available on the
dell website is 1.1.4. Also, everyone says version 1.1.4 fixes thier problem,
but I am still experiencing it...

Also, I can't find out how to install this bios... I don't have windows
installed, and I can't get it to run on a FreeDOS disk -- says something about
"wrong system"...?
Comment 33 Zach Spoelstra 2007-06-08 04:16:35 UTC
Just wanted say this is still a problem here with my C521.  I've tried bios
versions 1.1.4, 1.1.6, & 1.1.8 and all show the same problems.  I've also tried
passing the different kernel parameters mentioned here and in other threads
around the net.

Additionally, once the mouse stop responding I cannot unplug it and plug it back
in like others say they can.  Also, if I continue to use the computer with just
the keyboard it will lock up itself after a short while.  The computer is still
responsive as I can ssh to it, but the usb ports (all 6) are totally unusable.

I'm using kernel 2.6.20 on Gentoo.  If you need any additional information just ask.
Comment 34 Natalie Protasevich 2007-06-13 17:47:04 UTC
I know this is a very pressing issue, only happens to some: two people next to each other with similar systems and configuration - and one has a problem and another one never does. I have similar problem except it's the keyboard that freezes and mouse never does. I can even press keyboard key but it takes "double pressure". Something to do with X too, because when my keyboard is half dead, the text console is OK, I can type just fine.
Anyway, pinging USB gods...
Comment 35 Jeana 2007-11-11 09:12:18 UTC
I have had this problem continually on a Gateway GT5056, with kernels all the way from 2.6.16 - 2.6.23, on Ubuntu Feisty / Gutsy, and Gentoo. I have a Gateway GT5056 with a custom Foxconn built for it, and they have no BIOS updates.
Once the mouse is lost, it is lost in both X & GPM. Like others, I am using a Logitech wireless mouse/keyboard combo, and the keyboard continues to work fine. Unplugging and then plugging back in simply loses me the keyboard as well, rather than restoring the mouse. Restarting XDM causes me to lose keyboard as well. No messages logged in dmesg or /var/log/messages. I have not been able to debug with usbmon as sometimes I can go a day or two without experiencing this bug.
It does seem to involve power management somehow though. This always happens right after I hear the fans start to spin up faster. Compiling the Kernel with no ACPI/APM/cpufreq support makes no difference. Starting with noapic, acpi=off, acpi=noirq etc. makes no difference.
Comment 36 Alan Stern 2007-12-31 12:39:51 UTC
Is there anybody listed on this bug who is willing & able to try out various kernel patches and do some serious testing?

There are so many different and conflicting reports above that it's impossible to sort them out.  Any real work will have to be some with only a single person, somebody who can reproduce the problem fairly reliably and quickly.
Comment 37 Bill Deegan 2008-01-14 23:43:19 UTC
What's involved in the testing?
I can build a kernel.
Any heavy lifting here, or just capturing log files and applying patches and building kernels?
Comment 38 Norbert Zawodsky 2008-02-06 11:12:53 UTC

Just FYI: Same problem here, Randomly mouse & keyboard freezes. Just waiting some seconds unfreezes both.


ASUS P4PE motherboard, Intel 845PE chipset
CPU: Pentium(4) 2.4 GHz
microsoft kbd/mouse combo over wireless USB tranceiver stick

Interesting is, that these "keyboard freezes" even when no OS is loaded!
Just enter Bios-Setup by pressing <DEL> while POST. Then move around the setup menus with the cursor keys. After 10 to 20 seconds the kbd freezes.

That "frozen" state "thaws" again after a few seconds.

Same behavior when Linux & KDE is up. Kbd+Mouse freeze every 20 to 60 seconds.

If interrupt mode in Bios is set to PIC, the problem is as described above.

If mode in Bios is set to APIC, the system is nearly unuseable. Mouse & kbd is frozen almost all the time.

If wired PS/2 kbd + mouse are plugged in too, they are both useable while the wireless ones are frozen.

I get the most "stable" system with BIOS set to PIC and boot kernel with noapic parameter.
acpi=off parameter doesn't seem to have any influence.
Comment 39 Natalie Protasevich 2008-04-01 20:31:41 UTC
Norbert, your problem is in hardware/BIOS if the mouse freezes with no OS loaded.

To all reporters:
If you still experiences problems with mouse, and you have different hardware than Nacho de las Rios, please open a separate bug.
For those who have Dell Dimension E521 - is the problem still there? There were probably updates to X server, and your distros, can you update the status on this problem please.
Comment 40 Stephen Reindl 2008-04-01 22:30:37 UTC

after upgrading to a recent BIOS version (1.1.6+) the problem seems to be no longer existant. My server is running now for about four month, whenever I use the windows system (even for hours), keyboard and mouse doesn't create any problems (except for typos, but this seems to be PLBKAC :-)).
