Hi Jostein,

This is interesting. Did you patch the rt sources at all or are you
running the kernel as it came from the repo ? Did you simply drop-in the
jackdmp version of jackd (./waf configure --prefix=/usr) or was any
other action required ?

Btw, I determined that the rt kernel was causing many of the troubles I
had with 8.10. Running the non-rt kernel eliminates those problems,
specifically the system hang at logout or shutdown. Of course, it also
leaves me without an rt-capable kernel. :(

Best,

dp
