Try disabling CPU Power Management on the BIOS.

I run -current on a T22 and still get some write/read fail codec when
suspending or returning from sleep.
When I get those errors after a resume and I try mplayer or anything
that uses sound I get flooded with errors on dmesg and the computer just
hangs for a bit until I kill the program that was using the sound card.
These are the errors:
clcs0: AC97 read prob
clcs0: AC97 write fail
The "fix" for me is to suspend it again and normally on the next resume
it's gone.
