[Bug kprobes/6707] New: oops crashes with 2.6.25 - onoffprobe

On x86 kernel 2.6.25 I regularly get hardware lockups caused by oopses when
running make installcheck. This is in particular with fedora 9 -
2.6.25.6-55.fc9.i686. The fedora 8 - 2.6.24 kernel was fine.
After setting up netconsole as described on
http://sourceware.org/systemtap/wiki/DeveloperSetupTips I collected various
oopses, which I will attached.
I cannot replicate this in a qemu-kvm environment, then there are some regular
make installcheck failures, but no kernel oopses. It only occurs on the real
hardware.
The test that most likely (but not always) triggers these oopses is
testsuite/systemtap.base/onoffprobe.stp, which can be explicitly run with make
installcheck RUNTESTFLAGS=onoffprobe.exp
