Hi,
I had to disable ACPI on my system because it caused a high
load. While rebooting I noticed that the second CPU (P4 HT) wasn't
found:
CPU: Trace cache: 12K uops, L1 D cache: 8K
CPU: L2 cache: 512K
CPU: Physical Processor ID: 0
Intel machine check reporting enabled on CPU#0.
CPU: After generic, caps: bfebfbff 00000000 00000000 00000000
CPU: Common caps: bfebfbff 00000000 00000000 00000000
CPU0: Intel(R) Pentium(R) 4 CPU 2.60GHz stepping 09
per-CPU timeslice cutoff: 1462.79 usecs.
enabled ExtINT on CPU#0
ESR value before enabling vector: 00000000

Error: only one processor found.

ENABLING IO-APIC IRQs
Is ACPI necessary for HT to work? This is with 2.4.21.
Cheers,
Jurgen
