[proaudio] realtime problems (maybe pam)

[Frieder Bürzele <evermind@xxxxxxxxxxxxx>]

Hi folks,

I've switched to amd64 and now hav the problem not getting realtime stuff running
ATM I'm using sabayon-gentoo-linux as a base -- later I want to switch to new gentoo install,
but for now I hav to get realtime stuff working with this distro

I think I've setup pam correctly (user into autogroup, params added to limits.conf),
pam version is 1.0.2


ulimit -r gives me 99
as set in pam securiy stuff

the kernel config gives me:

zcat /proc/config.gz |grep -v '#' |grep 'CONFIG_SECURITY'
CONFIG_SECURITY=y
CONFIG_SECURITY_DEFAULT_MMAP_MIN_ADDR=0


I'm using 2.6.27-rc6-git5: The config options
CONFIG_SECURITY_CAPABILITIES
is gone -- now it is compiled per default into the kernel


I don't think that pam fools me as set_rlimits also won't work:

set_rlimits -d /usr/bin/jackd -R -d alsa 
Matching config file entry: user/group=@audio, prog=/usr/bin/jackd, max_nice=-1, max_rt=85, max_mlock=-1
`nice' getrlimit returned 0;   current `nice' rlimits: soft=40, hard=40
`rtprio' getrlimit returned 0;   current `rtprio' rlimits: soft=99, hard=99

output with just pam
jackd  alsa gives me

jackd -R -d alsa

what else could give be the cause of not getting realtime stuff working?

thx
