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

[Robert]

One workaround for this bug is to start a sequencer before loading rosegarden e.g.:

 $ timitidy -iA

Then everything seems to work smoothly. 

Note that in current versions of dapper the module snd_seq_midi isn't loaded by default so you won't observe this behaviour until loading it with modprobe. 

My hunch is that the root cause of the problems is a bug in the alsa kernel module.
