When running the systemtap testsuite on a RHEL4 machine with the 2.6.9-37.EL
kernel, the systemtap.base/probesfunc.exp crashes the machine with the following
message on the console:
Linux slingshot.devel.redhat.com 2.6.9-37.EL #1 Fri May 19 17:55:44 EDT 2006
i686 athlon i386 GNU/Linux
Kernel panic - not sync: kernel/module.c:2114:
spin_lock(kernel/module.c:c036b280) already locked by kernel/module.c:2114
Badness in panic at kernel/panic.c:118
systemtap.base/probefunc.exp definitely causes the crash when trying to probe
kernel.function("scheduler_tick"). I don't have a great deal of details about
the failure on the RHEL4 UP kernel. There wasn't a traceback or oops on the screen.
