Software Environment: During Boot-up
Problem Description: Kernel stalls while initializing ehci_hcd
last output while booting:
GSI 19 sharing vector 0xC1 and IRQ 19
ACPI: PCI Interrupt 0000:00:03.3[D] -> GSI 23 (level, low) -> IRQ 19
ehci_hcd 0000:00:03.3: EHCI Host Controller

this has been tested with both gcc-3.3 and gcc-3.4.
Odd enough, sometimes this happens when the notebook is plugged in, and as of
yet failed every time to boot as soon as it runs on battery.

Steps to reproduce:

Comment 2 Maxxer 2006-01-02 13:34:02 UTC

This updated DSDT

http://acpi.sourceforge.net/dsdt/view.php?id=528

SOLVES THE PROBLEM!!

Comment 3 Maxxer 2006-01-03 02:02:36 UTC

well, should... I still have bios 206 and further tests tell me it's not enough
(ehci still crashes). I'll try the new bios and report back.

Comment 4 Greg Kroah-Hartman 2006-01-04 14:31:23 UTC

Marking closed.

Comment 5 Maxxer 2006-01-05 01:06:09 UTC

why did you close the bug? It's still unsolved!

I tried upgrading bios but sadly it didn't solve the problem.
I tried 2.6.12 and it seems not to crash. I booted at least 4 or 5 times, from
battery, without problems.

Comment 6 Greg Kroah-Hartman 2006-01-07 15:42:02 UTC

Sorry, I saw comment #2 and thought it was fixed.

Comment 7 Maxxer 2006-01-19 07:41:48 UTC

someone reported me that completely disabling ACPI from kernel makes the pc boot
fine and correctly load the ehci module.


This guy in Gentoo forum 
http://forums.gentoo.org/viewtopic-t-414765-highlight-a6k.html
said he solved the problem by fixing the dsdt. Sadly I can't contact him.

Comment 8 Greg Kroah-Hartman 2006-01-23 12:39:07 UTC

Sounds like an acpi issue, reassigning...

Comment 9 Greg Kroah-Hartman 2006-02-14 17:51:13 UTC

This might be fixed in 2.6.16-rc4.  Can you test that out and let us know?

Comment 10 Maxxer 2006-02-15 08:51:54 UTC

You can bet I will, as soon as it get available! :-)

Comment 11 Maxxer 2006-02-19 02:03:22 UTC

I've installed the kernel yesterday, and IT SEEMS TO SOLVE THE PROBLEM!
I tried warm and cold boot, from battery and AC, and every time it loaded the
ehci module correctly without crashing.
I will do further tests today and tomorrow, and will report back again!

So far, THANK YOU A LOT!

Comment 12 Maxxer 2006-02-23 03:05:40 UTC

I've been using the new kernel for some time right now.
I've done cold and warm boots, with and without AC, and the module was loaded
every time without crashing. 
I've also attached an USB2 device, and worked fine.

To me, the thing is solved, THANK YOU AGAIN!


I got negative response from a french friend using an ASUS A6Km still concerning
ACPI/EHCI, but I don't know if it's strictly related to this bug.

I also wrote a mail to two other friends who experienced the kernel hang, but I
still have to get a reply from them.
I will post here any other news.

Comment 13 Paweł Szczekutowicz 2006-03-02 11:06:55 UTC

On A6Km / AC connected - when booting with usb mouse pluged-in kernel hangs just
after infomartion about processor type. When nothing is connected to usb
everything works fine ( battery status, processor stepting, acpi thermal shows
correct temperature ) and after full system boot when i connect usb mouse it
works without any problems...

Comment 14 Paweł Szczekutowicz 2006-03-03 09:14:24 UTC

it hangs on evxfevnt ( evxfevnt-0091 )

Comment 15 Greg Kroah-Hartman 2006-03-06 10:53:46 UTC

Ok, closing as fixed, as the original bios fix is in the kernel tree.

If you still have other problems, please open them as new bugs.
