Screen capture from xSeries 445 rsm with maxcpus=4
Something's funny here. I have a quad xSeries 445 with hyperthreading turned
on. When I boot with MAXCPUs=4 the system takes a SCSI failure on the MPT
driver, and hangs, without booting.
If I set MAXCPUS=6, MAXCPUS=2, or MAXCPUS=0 everything's fine...
See attached screen capture.

This issue is beyond the scope of the current support status of RHEL2.1. No fix is planned at this time. |
