Two OOPSes in ALSA with kernel-2.6.17-rc1

[Shlomi Fish <shlomif@iglu.org.il>]

Hi all!

(Please CC me on the replies)

I recently received these two OOPSes with kernel-2.6.17-rc1. They happened 
while mpg123 was playing a WAV file and I invoked KDE (along with artsd).

My soundcard is snd_intel8x0.

Let me know if you need any other information.

Regards,
