Hi... anyone out there also having problem with this combination?
188.8.131.52 or 184.108.40.206 with 220.127.116.11-rt11 and alsa MIDI
It looks to me like alsa midi is broken.
Probably an interaction with the realtime kernel patch. A Fedora kernel
based on 18.104.22.168 (22.214.171.124-49 on fc8) works fine, a very similarly
patched kernel that includes the realtime patch does not. The
configurations for both are almost the same (today I tried to change
some of the most obvious differences and rebuild, with the same
No problems with 126.96.36.199-rt21.
Test: boot, login, plugin an external usb keyboard (Yamaha P250), it is
recognized, use qjackctl alsa patchbay to connect it to kmidimon,
kmidimon sees only _one_ midi message and that's it. Kmidimon can't be
killed after that.
