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.
Version-Release number of selected component (if applicable):
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
system is up and running smp kernel
Can you reproduce the issue with latest RHEL4.6 kernel?
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?
