Seeing this problem as well.  As far as I can determine right now, it is test
frysk2130/strace-clone-exec.sh causing it.  It is mostly reproducible, though I
have been able to do full 'make check' runs on my frysk build that do not
trigger it, occasionally.

Quick follow-up - did a reboot and executed just the strace-clone-exec.sh test
from the command line.  This also triggered the kernel bug, on FC6 with the
2.6.19-1.2895.fc6 kernel.

Anyone out there with the latest RHEL5 beta installed who could verify whether
this problem occurs there also?

This is actual a kernel bug (as stated in the original bug that prompted this
testcase to be added - #2130).  However, note that the testcase is *not* testing
the kernel bug in the sense that the testcase passes happily while it still
often (but not always) triggers the kernel bug.

So, noteworthy info:
- This is definitely a kernel bug
- The test case passes even if the kernel bug is triggered
- The kernel bug is not 100% reproducible - it sometimes takes multiple attempts

Reopening after talking to Mark.  We believe this is not actually the same
problem as 2130, but rather a similar case (occuring in a slightly different place).
