jrun works fine, although it uses rtai_ksched.ko instead of rtai_lxrt.ko. Itt still leaves some processes running:

Regarding our main problem (-> 3.3 test4: Stuck in rt_task_wait_period()): Unfortunately our stuff is much more complex than posix/user/condtest.c with lots of IPC happening between hard and soft real-time tasks. Our freezes only happen after several minutes of processing and after >>10000 periods of the HRT task (some ugly race-condition?).

We use glibc_i586 from SUSE 9.3 which includes linuxthreads (cpu is a "VIA Samuel 2" which does not like i686-kernel/glibc)
