Thank you for the suggestion, David. I tried booting both with "noapic
nolapic" and in failsafe mode, but both the error message and the symptom
remain.
Looking through the dmesg output under 10.0, where sound works fine, I saw
that there the device 00:1f.3 ("SMBus: Intel Corporation 82801CA/CAM SMBus
Controller (rev 02)") does not have an IRQ associated with it, so that the
sound card 00:1f.5 ("Multimedia audio controller: Intel Corporation
82801CA/CAM AC'97 Audio Controller (rev 02)") doesn't have to share it.
Does that give anybody any clues?
