Bug Description
I just got a brand new Thinkpad T61P and I've installed Ubuntu on it (after working through some troubles). In hopes of getting wireless working (the hardware is iwl4965-based), I upgraded to gutsy. Unfortunately, the kernel crashes during boot when the wireless is enabled via the "kill switch." The kernel trace doesn't appear to be dumped into any files, presumably because it kills the kernel so abruptly.
The symptoms are that a little way through the initial boot, the progress bar stops, and the caps lock LED blinks on and off.
If I boot in "rescue mode," after exiting the prompt to allow the boot to continue, it gets a ways through the process then dumps a bunch of kernel crash data, more than a screenfull.
Under feisty, of course, there were no 4965 drivers, so there's no crash when using the 2.6.20 kernel.
It appears that switching the kill switch back on after a successful boot does not lead to a crash.
