Catnip Kernel Panic
Thanks to BoingBoing, I now have a new all time favourite bug report (although, in all honesty, I didn't have a favourite bug report before this one).
From the report:
'I encountered a kernel panic with the 3.1.0 kernel on a Dell Latitude E6410 while inputting simultaneously from the integrated keyboard with a cat and from the external keyboard myself. I was trying to type my password with the external keyboard (pw dialog already visible), but I noticed that the computer didn't seem responsive to my typing. Then suddenly the cat shifted his position and there was a kernel panic involving input handling. I'm now using i8042.nokbd kernel parameter as a workaround, something I've found useful also earlier.'
Follow up comments to the bug report inlcude: 'Yes, it was a catastrophe', and 'Your cat wanted to find out what the magic in "magic SysRq key" means and pressed Alt+SysRq+C. The problem is that he did not consult Documentation/sysrq.txt first; the "C" does _not_ stand for "catnip".'
