[linux-audio-user] kernel2.6: realtime lsm and allcaps=1

   Hi to the list,
I've installed a Debian Sarge with kernel 2.6.6, jack 0.94 and 
realtime-lsm 0.1.1 to have the realtime capabilities for the normal user.
The default is to set gid=<audio_group_gid>, but I'm not able to start 
jack from a user in the audio:

$ jackstart
jackstart: cannot get realtime capabilities, current capabilities are:
            =ep cap_setpcap-ep
     probably running under a kernel with capabilities disabled,
     a suitable kernel would have printed something like "=eip"

Neither the any=1 parm does the job. If I reload the module with the 
allcaps=1, then I can start jack from a normal user.

Am I missing something? Is not insecure to run jack via allcaps=1?

Anyway, with the 2.6 series I've got a lot of xruns. I've read that 
maybe the problem is, instead,  with the new version of libc. Someone 
knows more on it, and is there some workaround?

Thanks,
- Antonio
