Latest working kernel version: I remember it was working 3-4 years ago.Don't
remember which kernel I was using at that time.

Distribution: ubuntu 8.04,8.10 and opensuse 11.1
Hardware Environment:
x86, soundcard is a soundplaster audigy 2 zs

Software Environment: using asfxload and aconnect

Problem Description:
When I load a soundfont in the sound card and try to play any note from it, the
computer freezes after ~1 second.

Steps to reproduce:
-load a soundfont in the soundcard 
$asfxload myfont.sf2
-connect a midi source event to one of the emu10k1 wavetable ports
$aconnect -i (see the list of midi sources)
$aconnect -o (see the list of midi destinations)
$aconnect 20:0 17:0 (connect a midi source to a midi dest)
-have your midi source play any midi event (I use a midi keyboard, but I tried
it with a midi software as well)

Computer just freezes (doesn't reply to ping anymore) and doesn't leave any
message in /var/log/messages.
