Hi all,

with 2.5.41 I can't type the " | " anymore. If I type it, I get

atkbd.c: Unknown key (set 2, scancode 0x6a, on isa0060/serio0) pressed.
atkbd.c: Unknown key (set 2, scancode 0x6a, on isa0060/serio0) released.

relevant part or dmesg (I hope):

register interface 'mouse' with class 'input
mice: PS/2 mouse device common for all mice
register interface 'event' with class 'input
input: PS/2 Generic Mouse on isa0060/serio1
serio: i8042 AUX port at 0x60,0x64 irq 12
input: AT Set 2 keyboard on isa0060/serio0
serio: i8042 KBD port at 0x60,0x64 irq 1

Moreover, sometimes the usb mouse dies. Pulling it out and plugging it back
gives me

Debug: sleeping function called from illegal context at
include/asm/semaphore.h:119
