From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3 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. Howard Version-Release number of selected component (if applicable): kernel-2.6.9-5 How reproducible: Always 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 Additional info:
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?
