Serious kernel bugs?
by Callum Lerwick
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...
