it seems to work fine. With the above enabled it hangs on both of my
SMP systems as described above. :-/
ahh ... i'll try to reproduce it that way.
found the bug - it was the incorrect initialization of
debug_slock/rwlock. I've uploaded -48-02 with the fix. This release also
includes a new debugging feature: CONFIG_DETECT_SOFTLOCKUP, which works
similar to the NMI watchdog but detects soft (==no reschedules) lockups.
I've also converted a few more local_irq_*() calls to raw_local_irq_*()
calls.

Sorry for not reporting back sooner on this, I just kept getting
interrupted. My problems seem to be resolved on my SMP systems, even when
CONFIG_DEBUG_RT_LOCKING_MODE=y
I should note that I didn't actually try with the version above because
it had been updated before I got to it.
