Subjectrealtime-preempt 2.6.16-rt7-10 bug?
i've compiled the 2.6.16 kernel with the realtime-preempt patches, but
have run into some problems while using Ardour for realtime audio.
Ardour crashes whenever i stop recording, and after running dmesg i'm
suspecting a bug in the realtime patch (i've tried rt7 and rt10, both
have the same problem):
