Description Nobuhiro Tachino 2007-08-07 14:54:48 UTC 
Description of problem:

Diskdump fails on MPT/Fusion since RHEL4-U6-re20070804.0

Version-Release number of selected component (if applicable):

2.6.9-56.EL

How reproducible:

Always.

Steps to Reproduce:
1. Create a diskdump partition on SCSI disk that is connected via MPT/Fusion.
2. Enable diskdump service.
3. Cause panic.
  
Actual results:

Diskdump hangs to wait the completion of host reset.

Expected results:

Diskdump succeeds.

Additional info:

I think this is a regression caused by the update of of MPT/Fusion driver.
The driver on RHEL4U6 does not have some code of diskdump, which existed
on RHEL4U5. The appended patch restores the code. I tested the patch and
confirmed it fixes the problem.
