Description Jeff Kuehn 2009-04-07 20:56:09 UTC

Description of problem:

Dell D630 Laptop (Intel T7500, G965, Intel 3945 wireless) experiences a kernel panic shortly after attempting to connect to infrastructure access point with WPA/WPA2 Enterprise / PEAP / PEAP Version 0 / MSCHAPv2 (panic sometimes occurs immediately, sometimes after a few rounds of drop/reassociate).

Version-Release number of selected component (if applicable):

2.6.27.21-170.2.56.fc10.x86_64

How reproducible:

Every time, though perhaps with a few cycles of drop/reassoc over a few minutes. This has been occuring for a few months, but the system it wasn't until today that I was able to capture a trace from the panic.

Steps to Reproduce:
1. Using NetworkManager Applet 0.7.0.99, select WPA/WPA2 Enterprise network
2. (reassociate to this network if connection drops before panic)
3. System panics
  
Actual results:
The panic generally occurs during an X session and a console cannot be recovered to obtain a trace, however, *ONCE* I've been lucky enough to have the panic occur while I was switched into a VT. The system was totally frozen, but I was able to capture a few photos of the last screen of the trace with my phone. The result is transcribed below:

---[ end trace 32831e314c3902ae ]---
Kernel panic - not syncing: Aiee, killing interrupt handler!

Expected results:

Wireless does not cause a panic.

Additional info:

I'm not changing the rate control setting, so I believe it's using the default of PID.

This problem is specific to the above WPA/WPA2 Enterprise config. Panics do not occur on a WPA2-PSK network.

Google finds a lot of panic messages in rate_control_get_rate.

The laptop's battery is completely consumed within a few minutes of the panic, generally meaning there's little or no time respond.

Engaging the rfkill switch prevents panics.

Comment 1 Jeff Kuehn 2009-04-09 17:52:37 UTC

Upgrading to kernel 2.6.29.3 form koji seems to improve the system stability with regard to panics.  

The wireless connection still drops and restarts every few minutes. Below is a cut from /var/log/messages showing a drop/restart

Comment 2 John W. Linville 2009-04-27 15:15:38 UTC

"Upgrading to kernel 2.6.29.3 form koji seems to improve the system stability with regard to panics."

Closing on that basis.  Please open a new bug specific to the problem described in comment 1 if that issue persists.
