Description Alexander Kaltsas 2009-06-24 14:54:42 UTC 
When using rt73usb driver for my wireless usb rt73 based card the system crashes. This doesn't happen immediately after the module is loaded. It happens when the software tries to bind the card with a wireless network (retrieve i.p. for the card via dhcp e.t.c.).

There is another weird thing going on with the usb. If I start my system with my usb mouse (15d9:0a33) there will be a kernel panic when trying to move the mouse. Removing the mouse (no mouse plugged in, or only one ps2 mouse) doesn't solve the problem. The system will crash when asking for an i.p. from the router. If I plug another mouse I have (046d:c51a) the system doesn't kernel panic. Removing my rt73 based wireless card or disabling the network tools that uses this card solves the problem. I can't fully understand if this is an issue that concerns only the rt73usb driver or is a generic issue for the usb kernel driver.

The system doesn't alway kernel panic. Some time it produces an Oops message and will panic some time later. Usually when trying to start X.


Steps to reproduce:

Try to boot a system using rt73usb without any pointing device or with the 15d9:0a33 mouse.

Comment 2 John W. Linville 2009-06-24 15:01:17 UTC 
That sounds icky...I'm not really sure where to start...
Comment 3 Alexander Kaltsas 2009-06-24 15:09:36 UTC 
I am not really sure that the particular driver causes the fault. I could be something that concerns the kernel usb driver. I was surprised by the fact that the system works with another mouse plugged and doesn't work with no mouse at all. The only sure thing thing is that when rt73usb driver isn't used everything works.

Comment 4 Alexander Kaltsas 2009-06-26 12:38:42 UTC 
I have to be a more general usb related issue. More and more user are having problem with kernel panic related with a usb device.

I want to have a look to possible changes made to the usb general modules.

Did you found anything related considering rt73? At least to exclude this one.
Comment 5 tomas m 2009-07-13 23:05:10 UTC 
same happens here, using various kernels (2.6.30, 2.6.31-rc2-git8 , git9)

the problem seems to go away from one build to the next, and then reappear.
it always happens when starting the network, attaching the kernel Oops log.

Have a look to the following bug.

http://bugzilla.kernel.org/show_bug.cgi?id=13681
Comment 7 tomas m 2009-08-04 13:30:42 UTC 
that bug was closed as irreproducible by you. im still experiencing these Oopses. usually after several hours of uptime. more rarely, during a wlan0 connection.

what i can find in common with all these oopses, is that the last sysfs file is /net/wlan0/statistics/collisions. im too much of a noob to further debug this, although im quite confident in patching and building custom kernels.

this particular Oops was triggered after a 'lsmod' command. (lsmod froze)

the Oops reports look like this one:

Comment 8 tomas m 2009-08-21 12:51:03 UTC 
ive built latest kernels with the following debug options enabled + CONFIG_TIMER_STATS

$ cat config | grep DEBUG | grep -v "#"
CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC=y
CONFIG_SLUB_DEBUG=y
CONFIG_HAVE_DMA_API_DEBUG=y
CONFIG_X86_DEBUGCTLMSR=y
CONFIG_AIC7XXX_DEBUG_MASK=0
CONFIG_AIC79XX_DEBUG_MASK=0
CONFIG_SCSI_MVSAS_DEBUG=y
CONFIG_JFFS2_FS_DEBUG=0
CONFIG_DEBUG_FS=y
CONFIG_DEBUG_KERNEL=y
CONFIG_SCHED_DEBUG=y
CONFIG_SLUB_DEBUG_ON=y
CONFIG_DEBUG_PREEMPT=y
CONFIG_DEBUG_BUGVERBOSE=y
CONFIG_DEBUG_MEMORY_INIT=y
CONFIG_DEBUG_RODATA=y
CONFIG_DEBUG_RODATA_TEST=y

with these changes in the kernel config (just enabling kernel debug and enabling collecting timer statistics) which i did to sort out power consumption issues. 

after doing this, ive received no more kernel oopses, i can keep the notebook on for over a day without an issue.
Comment 9 Alexander Kaltsas 2009-08-21 19:16:32 UTC 
The problem seems to be quite random. After a clean install about 20 days ago I have only received the Ooops message and a kernel panic 4~5 times. The first 10 days or so after continuous reboots an extensive use of the computer there was no sign of the problem.

Comment 10 tomas m 2009-08-23 23:58:50 UTC 
could you try and build a kernel with the .config settings i pasted above enabled?

i would provide the entire .config but i did strip out many device drivers. if you still want it, let me know.

i still havent suffered from a single Oops.
Comment 11 Alexander Kaltsas 2009-08-24 15:43:09 UTC 
I will give it a try.
Comment 12 John W. Linville 2010-03-05 18:53:28 UTC 
Closed due to lack of response...
