Re: Soundcard freezes after a suspend...

Cameron do you think this is okay for me to commit to -current and then to 
-stable after a week.  I've been running this on -stable.  It compiles in 
-current and I don't see why it wouldn't work there.  However, my laptop 
doesn't like to suspend and resume very well in -current so it's hard to test
there.  Also it's a bit of a hack and I was wondering if you as the sound
guy had any objections.  It better then the now when sound is dead after
a resume and needs either a kldunload/kldload cycle or worse a power cycle.

Thanks,

Doug A.
