RHEL5 bootlog from dell-per605-01.rhts.bos.redhat.com

Description of problem:

jburke is testing out a method of simulating 1 cpu systems by setting "maxcpus=0" as a boot parameter.

Version-Release number of selected component (if applicable): RHEL5-Server-U3-Default

How reproducible: 100%

Steps to Reproduce:
1. Boot dell-per905-01.rhts.bos.redhat.com with "maxcpus=0"
Actual results:

See attachment for boot log.

Expected results: No softlockup warnings should be seen and the boot should continue.

thenzl -- I doubt that this is an mpt driver issue and has more to do with specifying "maxcpus=0" on the bootline.

I just added you in case there is a problem with the mpt driver.
