I installed the updated device-mapper-multipath package i.e.
device-mapper-multipath-0.4.7-12.el5_1.2 on my RHEL 5.1 root device multipathed
host and rebooted, but the host freeze is still reproducible during faults. As
suggested by Kiyoshi, I ran the attached script i.e. test.sh to trigger the
freeze (the freeze is also reproducible while running FC path faults on the SAN

I don't see any prio callout binaries in /var/cache/multipathd/ (if that was
intended in the fix). The sysrq dumps (taken 10 minutes apart) seem to show both
multipathd & bash stalling on the exec system call (similar to the original case).

Martin, please open a new bugzilla (clone this one) since this is marked closed

This is a clone of a 5.1 async errata that did not fix the partner's issue. (bug
428338). I'm going to close this as a dupe of the original 5.2 issue.
