Summary:                    Kernel panic on use of hardware MIDI synth
Description: 
I've just upgraded to 1.0.10 from Fedora's 1.0.9, and now I have access to
my soundcard's (SB Live! 24-bit) MIDI synth.  However, any attempt to use
it causes a kernel panic, something about a spinlock.  My other MIDI port
(connected to a musical keyboard via a USB adapter) works fine.  Both
snd_mpu401 and snd_mpu401_uart load without problems.  I thought this
error might be related to 1623, so applied the supplied patch, but to no
avail.

Um, the SBLive! 24 bit does not have a MIDI synth.

Please post the kernel panic here.

It doesn't?  Ah, well that would explain the panic.  Is there any way to
disable the MIDI port ALSA creates so that applications don't try to use
it?

And... how exactly do I post a kernel panic?  It goes by far too fast to
memorize or write down.  Is there a log?

I'm thankfully inexperienced in the area of kernel panics :-)
