MRG-RT kernel panic on DL580 G7

Solution Verified - Updated -


On a newly installed HP DL580 G7, the server boots fine using the normal RHEL kernel, but panics in trying to boot the MRG Realtime kernel.

The console is filled with messages:

udevd[2941]: worker [3136] unexpectedly returned with status 0x0100
udevd[2941]: worker [3136] failed while handling '/devices/pci0000:00/0000:00:09.0/0000:08:00.0'

This PCI ID corresponds to an Emulex FibreChannel HBA card.
