[Bug 34831] Re: Hardlock of entire system (Dapper Flight 5)

[Alberto Torres]

I think it's not hardware-specific, because the same issue happens in a
laptop with a very different hardware, different soundcard, video,
proccessor, chipset, everything.

Sometimes rosegarden may start up and nothing happens. Then I fire up
some midi synth (such qsynth, zynaddsubfx, timidity) and bye bye.
Sometimes zynaddsubfx alone also crashes the system.

I'll provide the debugging info tomorrow, now I'm in a hurry.

My friend's laptop soundcard is snd-hda-intel, mine is an sb live

BTW, what happened with mixer controls? they're screwed up, while
recording it doesn't work as expected, distorting one channel or muting
the other one; even sometimes I can't record at all (tried alsamixer,
alsamixergui and kmix).
