[linux-audio-user] RLIMITS and /dev/rtc for MusE

Hello dear audio users!

Recently i upgraded to a 2.6.13-rc6 kernel and since then i wasn't able
to use realtime-lsm anymore (error when loading the module). Now i
switched to rt RLIMITS. Therefore i had to bring back PAM on my nice
PAM-free system (i don't like PAM i have to admit).

Now i have some problems with it: i can't start MusE sequencer anymore
as user because:

------------
MusE: watchdog process 18591 _NOT_ running SCHED_FIFO
cannot set ticks 1024 on /dev/rtc: Permission denied
precise timer not available
------------

With realtime-lsm everything worked fine.
I think I've set up pam-login and /etc/security/limits.conf correctly.
At least i can start jackd as user with RT privileges, so I assume it's
working.

Could it be that i forgot something? The rights on /dev/rtc never
changed, so i think it's a) wrong setup from my side, or b) a
malfunctioning RLIMITS. I don't want to change the permissions for rtc
as it worked fine with rt-lsm.
Any help would be appretiated.

Regards
Tom
