SubjectSound card problems after 2.0.{8->,10} kernel upgrade
Hi all,

Yesterday we upgraded from kernel 2.0.8, whose operation seemed fairly
unremarkable (except for some possible ppp packet loss). This morning I got
this from my cronjob which plays music to wake us up:

/dev/dsp: Device or resource busy

The sound card is a straight GUS with 1MB of memory and no extra features;
the sound driver is a module.

Fortunately it's an alternate alarm system right now, so we don't have to
depend on it. All attempts to output to the sound card result in the above
`busy' message. The module cannot be unloaded:

sound: Device or resource busy

The console has this message from last night:

Jul 30 23:53:37 LiONS kernel: Sound: Audio queue3 corrupted for dev0 (0/16)

We've had off-and-on problems with sound, though lately it hasn't been bad
(mostly we've been running the 2.0.0 kernel).

Starting at about uptime one hour, the log looked like this. Normal
operational messages were interspersed, nothing at all unusual. However,
I have not deleted any messages immediately preceding a `last message
repeated'....

Hope this helps, let me know what other information I can provide.
