Description Shuo Li 2002-05-10 00:13:55 UTC
Description of Problem:

Pensacola's kernel already has files to support Hyper-Threading features in 
Intel processors. But the boot command line in lilo.conf or grub.conf need to 
have acpismp=force to enable this in default.
Version-Release number of selected component (if applicable):
2.1 Gold Master

How Reproducible:
Install the OS on one the following platforms:
SuperMicro DP
IBM xseries
Intel Shasta

Steps to Reproduce:
1. Install OS login as root 
2. Goto /proc/
3. Open cpustate(?) or simple type xcpuinfo

Actual Results:

see n-number of CPU in N-way system

Expected Results:

see 2n logical CPUs on N-way system

Are you using pre-production BIOS revisions?  We have tested this
successfully on multiple HT machines in our lab.
