(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...
