Description of problem:
I have a new Sun Fire x4600 M2 server with 2 dual-core AMD opteron processors. After RedHat AS 4 64bit was loaded, only one processor can be seen from OS level. When I tried to load smp kernel, it hangs right after hitting "enter". I already appended "nmi_watchdog=0s" to lines starting with "kernel" on /boot/grub/menu.1st. 
Help is needed to see all 4 processors. Thanks in advance.

How reproducible:

Steps to Reproduce:
1.boot x4600, see all 4 processors during POST
2.at grub menu, select smp kernel to boot from.
3.system hangs right away

Actual Results:
system hangs

Expected Results:
system is up and running smp kernel

Can you reproduce the issue with latest RHEL4.6 kernel? 

Comment 2 Mark Williamson 2007-11-21 15:55:30 UTC
I've tried RHEL4.6 (2.6.9-67.ELsmp) on a Dual-Core AMD Opteron(tm) Processor
2210 HE stepping 02. The machine actually boots now in comparison to the hang on
RHEL4.5, but then hangs randomly around 5-10 mins later. There are no error
messages associated with this hang. Is there anything I can do to enable
debugging of this so that I can give you people something to go on?
