Looks to me like you patched a SuSE kernel with I-pipe, did you? I'm
also running SuSE, but I always use a vanilla kernel as platform for
Xenomai. The config can be migrated from the original system (except for
the known ACPI / CPU-freq issues).

Time to upgrade, 2.2 is out :). BTW, there is one potentially relevant
fix even post 2.2: if you have CONFIG_DEBUG_SPINLOCK on, switch it off
or upgrade to I-pipe 1.3-08.

If you did use a vanilla kernel: any chance to grab the oops after the
crash? Or is it a hard lock-up? The best to get those oopses out are
serial console redirection or netconsole, see
linux/Documentation/serial-console.txt or
linux/Documentation/networking/netconsole.txt.
