SubjectCamino 2 (82815/82820) v2.4.x eth/sound related lockups

I'm experiencing hard lockups on my Intel Camino 2/Celeron 550
box with onboard sound/video/ethernet. Another box with the same
configuration has the same problems, so I think I can rule out
hardware problems.

I think this might be related to the eepro100 problem discussed
here last week as I see the same messages in syslog, but it
doesn't lockup when using eth alone. But as soon as I start xmms
and listen to a network stream - or just anything else that
uses /dev/dsp, it locks up hard within 5 minutes most of the
time - without writing anything anywhere.

Funny things in syslog include:

kernel: mtrr: base(0xe8000000) is not aligned on a
size(0x4b0000) boundary
kernel: eepro100: wait_for_cmd_done timeout!

Anybody any clues where to start looking?
