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
fabric).

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).

The attachment contains the following:

1) Config.txt - Config info of the RHEL 5.1 root device multipathed host.

2) test.sh - Script to simulate path faults.

3) msg-Jan31 - /var/log/messages

4) rhel5-1-dumps-Jan31.TXT - Sysrq dumps (taken 10 minutes apart) during the
freeze.
