earthforce_1,
I do not see the "Unable to reserve mem region" error message in your
boot messages. Do you see it if you type "dmesg"?. Do you have the
snd_hda_intel module loaded (check with "lsmod |grep snd_hda_intel")?.
Try to reload ("modprobe -r snd_hda_intel; modprobe snd_hda_intel") and
see if you see the error message.
Booting with the option pnpacpi=off makes the device functional. Could others
check if that is working for them too (I tried with apci=off, but system froze
during boot)?
By looking at similar issues
(https://bugzilla.redhat.com/show_bug.cgi?id=280641) this could be a bios bug,
I'll try to see if I have an update available.
