Just me
>Environment:
IBM Thinkpad 560X
4.8-RELEASE kernel, modified from GENERIC to include "options PNPBIOS" and
"device pcm" (as well as other stuff).
/kernel: pcm0: [CS423x] at port 0x530-0x537,0x388-0x38b,0x220-0x233 irq 5
drq 1,0 on isa0
(Note: I changed the greater/less-than signs to braces in the previous
paragraph.)
>Description:
After playing audio, suspending and resuming the machine, future
attempts to play audio result in:
/kernel: pcm0:play:0: play interrupt timeout, channel dead
>How-To-Repeat:
mpg321 ~/my.mp3
apm -z
(resume system)
mpg321 ~/my.mp3
>Fix:
Apply this patch. It may not be the elegant way, it may break other MSS
devices, but it's really simple and works on my 560X:
