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"
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.
