Hi all,
I have a P4 with Hyper-Threading that is acting wierd. Hyper-Threading is
enabled in the BIOS and the BIOS splash screen shows 2 cpu's. The problem
is that the kernel only recgonizes 1 cpu.
(indy pts1) # cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 2
model name : Intel(R) Pentium(R) 4 CPU 2.80GHz
stepping : 9
cpu MHz : 2800.839
cache size : 512 KB
physical id : 0
siblings : 2
runqueue : 0
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm
bogomips : 5583.66
(indy pts1) # uname -r
2.4.21-23.ELsmp
(indy pts1) #
I do see this message in dmesg:
SMP motherboard not detected.
Is there something I have to enable to get this to work?
Anyone have any idea why this is not showing both cpu's??
Regards,
Tom
