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.
I’ve never given thought to use an animal with multiple external peripherals when testing input load issues. Now I have one more reason to get another cat.
