Description of problem:

Kernel BUG at panic:74, invalid operand: 0000 [1] SMP

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

System is RHEL AS4/U2, Kernel is custom, built from kernel-2.6.9-22.EL.src.rpm
BUT with TWO modifications:

1) Increase CONFIG_NR_CPUS=8 to 16 in kernel-2.6.9-x86_64-smp.config

2) Workaround for reboot problem; hence this patch is applied:
