It has been reported in two cases that current.stp causes an NX protection fault.
http://sources.redhat.com/ml/systemtap/2006-q1/msg00157.html

The two kernels reported to crash are 2.6.14-1.1656_FC4smp.i686 and
2.6.9-30.ELsmp.i686. Both reports had a similar stack trace as well, starting with:
kretprobe_trampoline
do_timer
timer_interrupt
kretprobe_trampoline
Several other kernels and a different architecture (x86_64) were tested and did
not experience this crash.
