Comment 23 for bug 276990

linux-backports-modules 2.6.27-6.1 appears to fix this issue. I've run some large file transfer tests that easily caused the iwlagn module that comes with the kernel now to crash. But now running those tests with linux-backports-modules installed I no longer see the issue, and it doesn't crash at all.

I think most would prefer a non crashing module be apart of the regular kernel and not backports though. Hopefully later this week I'll have time to get a serial cable and see the crash

I was unable to get the kernel dump from the iwlagn driver as I really need a thinkpad docking station and getting kernel output out of USB serial ports seems like an impossible task.
