Hi,

I am getting a lot of these in the logs. This is with the ALSA emu10k1
driver for a SB live card. This is a x86, UP, KT133 system with preempt
enabled. The system seems to be running fine.

handlers:
[<d8986540>] (gcc2_compiled.+0x0/0x390 [snd_emu10k1])

BTW: What about the 4 i8042's on irq 12. Is this normal/OK?
