hibernate and pcm0

[LEI CHEN]

Hi guys,

I am running Freebsd 4.10R on my IBM Thinkpad A21p, I am using apm 
instead of acpi.

recently, i found a little problem, which is everytime the machine goes
to hibernate, and when it wakes up, the sound card pcm0 stop working. 

from log, I have this kernel mesg:
/kernel: pcm0:play:0 play interrupt timeout, channel dead

Has anyone here had the same problem? And any suggestion to deal with
this problem.

Cheers,
LEI
