Steps to reproduce:
I was actually trying to reproduce an error I caught the tail end of earlier
when I was trying to compile LTP. This doesn't look like the same error, and I
couldn't get a kernel compile or an LTP compile to cause an error for me again.
What I was doing when I got this error was running ltp (current cvs copy),
runalltests -q |tee /tmp/ltp.out
### ftest07 was the test currently running when it crashed
At the same time, I was also running variations on the aio01 test in ltp (not
currently part of runalltests)
aio01 -n100000
aio01 -c10 -n10000
### at this point nothing came back, so I'm uncertain as to whether it hung
before this test or hung as I executed it.
I went back and tried running all of these tests alone and had no failure. So it
could be somewhat random. I have not tested 2.5.69-mm7 or vanilla 2.5.69 in
this fashion but my regular runs of 2.5.69 vanilla did not expose this. If
there isn't enough to go on here though, let me know and I'll be happy to try it
on mm7 or 2.5.69, or do patch bisection if I can get a reliable way to recreate
the problem.
