Description Christopher M. Smith 2008-09-29 15:46:09 UTC

Description of problem:

I have been running both Fedora 9 and Fedora rawhide on an IBM x300 laptop.  I get frequent hard locks on the system requiring a full power cycle.  I have not found a repeatable way to get this to happen, but it seems to have something to do with a potential wireless networking issue on the host.  This behavior has been reproduced on both rawhide (what I'm currently running) and F9.

Version-Release number of selected component (if applicable): NONE


How reproducible:

Difficult to reproduce, but frequently occurs.  It leaves no sync'd log data.

Steps to Reproduce:

1. Start using the laptop.
2. After some period in time, system hard locks.  Is not responsive to sysrq.
  
Actual results:

Hard lock kernel panic.

Expected results:

Not a hard lock kernel panic.

Additional info:

Things I have tried:

* enabling sysrq on the system.  Is not responsive when it locks up.
* adding earlyprintk=vga to kernel command line.  No luck.

Output of things like lspci:

Comment 1 Colby Hoke 2008-09-29 21:38:04 UTC

Do you have a wireless switch on the side. Or a wifi catcher toggle by any chance?

Comment 2 Christopher M. Smith 2008-09-29 22:16:45 UTC

There is a wireless radio switch that turns wireless signals on and off at the hadware level, yes.

CMS

Comment 3 Colby Hoke 2008-09-29 23:22:24 UTC

Try disabling those in BIOS, if you can and see if it panics. Also, try appending pci=routeirq to end of kernel line in /etc/grub.conf

This was suggested to me recently and I've had no locks since.

Comment 4 Christopher M. Smith 2008-09-30 14:12:09 UTC

I have made this change and disabled all of the on-board wireless items I could and added the pci=routeirq option and still received the same type of non-sysrq capable panic.  Sorry :(

CMS

Comment 5 Christopher M. Smith 2008-10-03 15:52:14 UTC

I have done more testing on my end.  Here is what I have found.

1. I reverted myself via a fresh install to F9, leaving the BIOS items disabled and setting pci=routeirq as a kernel boot parameter.  I still had the panic issue.

2. I was comparing the environment differences between home and work and noticed that the majority of my panics take place at home.  I reviewed my wireless settings and noticed that while work uses WEP, I use WPA.  Further, my WPA settings on the router was set to expire the WPA group key every hour.  I changed this a larger threshold this morning and am currently experiencing the highest uptime that I've had in weeks.

I hope this helps a little bit in narrowing down the issue.

Thanks,
CMS

Comment 6 Christopher M. Smith 2008-10-03 16:08:13 UTC

And as if on command, 5 minutes after writing that message to you it panic'd.  Apparently I made less progress than I had thought.

Comment 7 Christopher M. Smith 2008-10-03 17:03:24 UTC

So I was able to capture a bit of debug by kicking off an intensive network process and all the open programs I usually use and switching to the F1 virtual console out of X.  Here is the (ugh) transcribed bit of the panic string I can actually see:

Comment 8 Christopher M. Smith 2008-10-06 21:06:37 UTC

Any ideas on this bug?  I'm sort of at an impasse here given that my laptop has an uptime of approximately 20 to 30 minutes at a given time, give or take the day.
I'm happy to reinstall or test anything that needs testing as that I've backed up all my data.

Thank you for your help.

CMS

Comment 9 Chuck Ebbert 2008-10-10 03:40:46 UTC

Same as bug 457154 in Fedora 9.

Comment 10 John W. Linville 2008-11-12 16:25:16 UTC

Are you using a .11n AP?  If so, can you disable .11n on the AP, or use a .11g AP instead?  Can you replicate the issue in a .11b/g or a .11g-only environment?

Comment 11 Will Woods 2008-11-12 17:35:52 UTC

Are you still seeing this with recent rawhide kernels? kernel-2.6.27.5-94.fc10 or higher should have a patch that will make this problem a warning instead of an oops/hard lock.

Comment 12 Will Woods 2008-11-14 22:30:27 UTC

Moving to F10Target - I think we've papered over the lockup, and nobody else has been able to reproduce the problem.

Comment 13 Charles R. Anderson 2008-11-18 01:18:00 UTC


*** This bug has been marked as a duplicate of bug 457154 ***

Comment 14 Christopher M. Smith 2008-11-19 13:13:03 UTC

will, +1.  I'm no longer locking up but I do see the "your kernel is generating diagnostic information and passing it along" graphical message within X.  The oops is definitely happening in some form, but its not preventing me from operating with wireless either.

Best,
