(am i the only one to be aware of this?)

midi is seriously broken on 2.6.26-rt, specially when driven outboard;
events delivered out of time if at all, outrageous jitter and
unpredictable drop outs; internally sequenced material (eg. queueing
events to a softsynth) might work barely but that is just little comfort.

note that this badness applies to PREEMPT_RT kernels >= 2.6.26, vanilla
is fine afaict.

all that trouble seems to be related to a regression in 2.6.26-rc2 that
just made the bkl non preemptible anymore, leaving the -rt people with a
herculean task to comply--look after Ingo Molnar's "Kill the BKL" tree
for news...
