[Pkg-alsa-devel] Bug#376382: alsa-base: MIDI playback on SB Live! 5.1 0220 combine with heavy disk activity = lockup

[Arthur Marsh]

Package: alsa-base
Version: 1.0.11-2
Severity: important


I initially thought I had a problem with denemo, but was able to 
reproduce a complete system lockup when playing MIDI files, given 
sufficient hard disk activity using:

aplaymidi -p17:0
playmidi -a
kmid

The first 2 were tried under twm, all 3 methods were tried under KDE.

Any suggestions on further debugging steps welcome.
