Bug Description
I'm having trouble with random intermittent crashes on Natty (Classic Desktop), on an Asus Eee PC 1015PEM-PU17. I've attached a screenshot of the crash, apport didn't catch a crash report for it. It's a hard crash, have to reboot. No apparent connection to any user action (I can be typing in a terminal/text document, surfing web browser, whatever).
There *might* be a connection to the Broadcom STA wireless driver, the crashes are apparently more frequent on a flaky conference network (but that's a purely subjective observation).
WORKAROUND: intel_idle.

From the dump there it seems to be in intel_idle. It might be worth trying booting with "intel_ idle.max_ cstate= 0" on the kernel command line to see if that resolves things for you. Please report any testing back here.
