Summary of nightly tests 20061109

Subject: Summary of nightly tests 20061109

Only four of the six machines reported results. fc6/rawhide i686 and
rhel4 i686 died. The ia64 machine results look to have a systematic
problem.

The fc6 i686 machine has page allocation failure in /var/log/messages.
"staprun: page allocation failure. order:5, mode:0xd0".
It looks like this is happening during sysetemtap.syscall/test.exp

The RHEL4U4 i686 crashes because of 2726, could we just blacklist
"scheduler_tick" and be done with it?

The RHEL4U5 ia64 getting unaligned accesses in staprun on the failed tests:
add.stp, div0.stp, equal.stp, inc.stp, etc.

The kernel.statement() is failing on the 64-bit machines.

The bench (0) test is failing on all the machines.

I will see about better characterizing the problems in encountered by
the testing.

The earliest record of staprun causing unaligned accesses on the ia64 machine is Nov 5. See things like the following in the systemtap.log output of dejagnu.
