dbench has intermittent hang on 2.6.0-test1-ac2
Summary:
dbench has been intermittantly not completing on uniprocessor. I run dbench 10 times. 1 of the ten runs has 1 dbench child that never gets started. That child is in sys_pause.
2.6.0-test1 and 2.6.0-test1-mm2 did not hang.
2.6.0-test1-ac1, 2.6.0-test1-ac2, 2.6.0-test2, and 2.6.0-test2-mm1 have hung. So it seems like a patch that Alan may have picked up first.
The hang has occurred on ext2, ext3, reiserfs, and xfs, so filesystem type seems unrelated.
pkill -9 dbench will let the processes continue.
dbench version 2.0.
