I've been having odd problems with music apps for a while now, and now
with kernel-2.6.17-1.2139_FC5, I'm seeing stuff like this:

That's what happens if I start qjackctl, then quit it.
I get this if I start qjackctl/jackd then try and start hydrogen:

With the previous kernel-2.6.16-1.2133_FC5, I just seem to get a total
system lockup in these situations, rather than the kernel recovering
itself and logging and error.
Anyone else seeing this? I'm guessing its time to file a bug...

Okay something really bizarre is going on, it may be two separate
issues. I went back to kernel 2.6.16-1.2122_FC5 and 2.6.16-1.2111_FC5,
and once again jack apps would segfault on startup. I determined running
jackd at a period of 256 somehow was causing this, even though I *swear*
it was working at one point. Backing off to 1024 worked fine.
Going back to kernel 2.6.17-1.2139_FC5, and running with a period size
of 1024 allowed me to run hydrogen for a bit, but when I quit hydrogen I
still got this:

The madwifi drivers are tainting my kernel, for some reason they keep
getting loaded even if I don't plug the card in. Though I've been
running madwifi this whole time so I doubt that its the problem. I'll
try nuking them entirely off my system. ;P
Still happening, even without the kernel taint:

This is after booting clean, starting up jackd with qjackctl, starting
hydrogen then quitting hydrogen. After this, any attempt to use the ALSA
sequencer just causes that process to hang trying to open /dev/snd/seq.
(kernel-2.6.17-1.2139_FC5)
Thanks, Callum.

I'm seeing kernel crashes, as well as simple hangs.
Is "aconnect -i -o -l" working for anybody anymore?
strace output shows it's hanging here...
access("/etc/asound.conf", R_OK) = -1 ENOENT (No such file or directory)
access("/home/green/.asoundrc", R_OK) = -1 ENOENT (No such file or directory)
open("/dev/snd/seq", O_RDWR
I'm running 2.6.17-1.2139_FC5.
