kernel panic when sending MIDI sequencer events

["Nathan Becker" <nathanbecker@gmail.com>]

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
