yes, 2.6.24 on this machine seems to produce test results similar to the
x86_64/2.6.24 results I posted (without the 64-bit failures of course).

You are right. It does contain:
SEE ALSO
       /usr/local/doc/systemtap*/examples
That should be updated to the location we decide that the examples will
be installed to (assuming they won't stay in
testsuite/systemtap.examples). I'll update it to say:
"For more examples see the stapex(5) manual page".

OK, I'll remove it.

OK. Dave, do you want to have them mentioned so people check them out
and give feedback, or is it too early for that?

Yeah, trying to get a better look idea now. dsmith pointed me at the
netconsole kernel support (this machine doesn't have a physical serial
port) to see if I can capture any output/oops/kprint with that. I'll try
to get that to work since qemu clearly does something to make the issue
disappear.

Cheers,

Mark
