everything works fine when I have to use it.
So you might give the 2.6.27-3-rt the last chance with some help from
jackdmp 1.9 (the upcoming jack 2.0). I have used jackdmp around 11
months now and it's IMO the only choice on a 64 bits machine with more
than one core. I also use jackdmp on my studio machine and are really
happy with it.
I hope this helps.
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,
