Hi all,
I recently switch from mandrake to debian and I have some problems when 
trying to upgrade the kernel.
I have installed the kernel-image-2.6.11, kernel-sources-2.6.11, 
kernel-headers-2.6.11-1.
Since no Debian packages exist for realtime-lsm-module for 2.6.11 
kernel, I decide to build from sources. I have link 
/usr/src/kernel-headers-2.6.11-1 to /usr/src/linux, compile 
realtime-lsm, install it all seems ok. The only problem was that 
realtime.ko was in /lib/modules/2.6.11/extra/realtime.ko.
As indicated in the realtime-lsm README I try to do "make 
modules_install" in /usr/src/linux but it does not seems to do anything 
so I manually "cp /lib/modules/2.6.11/extra/realtime.ko  
/lib/modules/2.6.11-1-k7/kernel/security/realtime.ko".
After that I could modprobe realtime any=1 mlock=0  allcaps=1 without 
error but starting jack with realtime privilege always return me this 
error :

Any ideas ?
