I'm using 2.6.26.8-rt ... I have no problems with USB MIDI at all, (am happily
running about 20 MIDI ports over 4 devices)...
I have not experienced slowness, the issues described above or increased latency
with this kernel at all.. The only thing I have noticed is on shutdown,most of
the system powers down except it fails to completely shut off the power and still
sends the last frame to the screen...
I have heard that 2.6.28 is actually very good even without the rt patches but
have seen on LAU that there are already 2.6.29 rt patches in progress.
