Description of problem:
only shows cpu0 and cpu1 when on smp
only shows cpu0 when not on smp
But this is dual xeon machine, and bootup says hyperthreading is enabled.
Tried noapic parameter...no effect
This is the motherboard:
no noht passed in kernel or /etc/grub.conf, ht just regular flag on
cpuinfo, everything in BIOS shows HT is enabled.
First it was 2.4.20-6smp, but now
2.4.20-24.9smp doesn't show improvement.
Realize errata for 9 will cease in April, but if it isn't too late
really like a possible fix. Hasn't been tried on Enterprise 3?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. enable Hyperthreading in BIOS
2. boot up into any linux 9 kernel
3. cat /proc/cpuinfo
Actual Results: In non SMP kernel: 1 processor
In SMP kernel: 2 processors
Expected Results: In non SMP kernel: 2 processor
In SMP kernel: 4 processors
Customer opened support case number 139877 with ASUS.
The non-SMP kernel will only ever show 1 processor.
duh, brain not in gear. I missed the fact that the SMP kernel was
missing the HT pairs. Hmm. Can we get dmesg output of the SMP kernel ?

sysreport bzip, should include dmesg entry
