Trying to get Jack running with a 2.6.5 kernel.
# modprobe -v realtime gid=102 allcaps=1

FATAL: Error inserting realtime (/lib/modules/2.6.5/extra/realtime.ko):
Invalid argument
Kernel was built with:
CONFIG_PREEMPT=y
CONFIG_SECURITY_CAPABILITIES=m
CONFIG_SECURITY=y
CONFIG_SECURITY_CAPABILITIES=m
CONFIG_SECURITY_SELINUX=y
That looks fine. But, the error you're getting normally indicates
that CONFIG_SECURITY_CAPABILITIES was not set to "m".
Did you set these?
CONFIG_MODULES=y
CONFIG_MODULE_UNLOAD=y
What does `grep Realtime /var/log/messages' say after modprobe fails?
When building LSM, I wasn't able de run make as a
user :
$ make
CONFIG_SECURITY_CAPABILITIES=m
make modules -C /usr/src/linux SUBDIRS=/home2/al/realtime-lsm-0.1.0
make[1]: Entering directory `/usr/src/linux-2.6.5'

But it works when make is run as root. The README file says that only make
install has to be run as superuser.
The way the Makefile currently works, it needs write access to the
kernel build tree. I'll update the README to make that clear.
I hope some day we will figure out a way to avoid modifying the kernel
build tree.
