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?

I had to install linux-source-2.6.17 version 2.6.17-2 as well as the ALSA
modules source from http://www.lxtec.de/debarchiv, then coax
module-assistant into creating modules with 2.6.17-1-686 version number,
but I finally installed the modules with the alsa-timer-irqsave.patch and
now MIDI playback on the wavetable of my SoundBlaster Live! 5.1 model 0220
sound card under kernel 2.6.17 works fine (-:.

Thanks for the help!
