Hello,
I have been running 2.5.5-dj2 for a week or so. About once per boot, I
get the following printk:
atkbd.c: Unknown key (set 4, scancode 0xb6, on isa0060/serio0) pressed.
Also, occasionally a key release event gets missed, usually a Shift key
but sometimes something else. I believe that this coincides with the
atkbd.c messages, but I am not definite.
I include below my boot messages for the purpose of describing my setup,
plus I include the output of /proc/interrupts in case it might be
relevant. Please let me know if any more information would be of use.
Cheers,
Wayne
