Problems with the intel8x0 driver

[Fredrik Smedberg <smedberg@swipnet.se>]

Hi!

I got a Fujitsu-Siemens 8830 laptop. It's equipped with a 3,06 Ghz Pentium 4 with hyper-threading and 1024 MB RAM.
The soundcard is a:

Previous versions of the kernel with older versions of ALSA always gave me this error:
Intel 810 + AC97 Audio, version 0.24, 01:22:57 Dec 27 2003

I got this error with kernel 2.6.5-rc1 using ALSA + the intel8x0-driver (the system ended up in a kernel panic):

Someone who knows what is wrong? Perhaps a serious bug in the intel8x0 driver? I've never gotten the sound-card to working under Linux using ALSA or OSS. The sound-card has so far only worked in Windows.

Thanks for all the help,
