>Description:
On IBM ThinkPad 240, ESS Solo-1 does not work after suspend/resume.
When I tried mpg123 after resume, it said that 'pcm0: play interrupt
timeout, channel dead'.
>How-To-Repeat:
Suspend/resume (or hypernation, wrong spelling?), then use pcm0 device.
>Fix:
I tried following patch and seems to work well for me.
(Sorry, It's cut and paste...)
I do not have any document about ESS Solo-1.
The patch is written by guess.
