[AIO] lockup on hammer
Last modified: 2007-11-30 17:06:57 EST
Description of problem:
It seems hammer kernels lock up when doing make check in rtkaio.
Reproduced twice on thor and once on romaine. Does not seem to lock up on other arches.
Version-Release number of selected component (if applicable):
rpmbuild --rebuild ~jakub/glibc-2.3.2-66.src.rpm
The call trace was inside __wtd_down_failed inside generic_aio_rw inside
The kernel is 2.4.21-1.1931.2.342.entsmp
*** Bug 103240 has been marked as a duplicate of this bug. ***
Takes about 5 minutes to reproduce using the aiotest
in Bug 103240, which also has a full console capture.
The arguments to wtd_down_common were swapped, causing the kernel to try to lock
something that wasn't a lock. Fix is in latest taroon.
Fix confirmed on Melody box in lab running 2.4.21-1.1931.2.421.ent.
