kernel panic when sending MIDI sequencer events

Hi,
I'm getting a kernel panic when a program sends a MIDI sequencer
event. Seems to happen in all recent kernels I've tested. Currently
I'm using 2.6.17.7 on an AMD X2 4800+ Nforce4 (Gigabyte K8NXP-SLI)
system running Slamd64 10.1 in 64-bit mode. I'm using the ALSA sound
modules for intel8x0 for the motherboard sound chip. I should mention
that PCM sound works fine, no crashes and sounds OK. If I understand
correctly, the intel8x0 does not directly support MIDI sound. I guess
this means I need to install Timidity or something to make MIDI sound
actually work, but this is of secondary concern. My primary concern
is that when programs send a MIDI event, it crashes the whole system.
Here is an excerpt from the error message as I've copied it from the console:
Call Trace: <ffffffff8038da4d>{rtc_control+56}
<ffffffff880b3063>{:snd_rtctimer:rtctimer_start+28}
...more stuff like that. Also mentions snd_seq:snd_seq_control_queue+153
snd_seq:snd_seq_deliver_single_event+281
snd_seq:snd_seq_deliver_event+337
snd_seq:queueptr+60
snd_seq_client_enqueue_event+119
Any help would be greatly appreciated. Please cc me directly.
thanks,
Nathan
