Summary:                    System freeze at end of MIDI playback
Description: 
Hardware: Sound Blaster Live! Value
Software: sfxload (for patch loading) and drvmidi (playback)

I often play a list of MIDI files. On a number of occasions---either at
the end of a MIDI song, or when I hit STOP---the computer has frozen hard.
The recurrence is rare enough to make this more an annoyance than a
showstopper, but then, I haven't been too keen on ferreting out this bug.

I am reporting this against ALSA from the 2.6.8 kernel, as that is what
I'm using now (Debian official package) but the same problem arose with
alsa-driver 1.0.8 (as compiled by me) on 2.4.29.

I could probably rig up something to start/stop MIDI playback repeatedly,
with a debug-compiled driver, but is there any way to get useful debugging
output when the bug takes the whole system down?

Having the same issue here (it seemed to be triggered by The GIMP - recent
CVS builds have a MIDI controller, and the freezes stopped when I disabled
it)

Kernel - 2.6.15-23-k7 (Ubuntu Dapper)
ALSA - 1.0.10-4ubuntu4
Sound Card - Creative Sound Blaster Live! 5.1 Digital

If you play back from a text console (aka without X running) does any Oops
appear on the screen?
