 |

Hi All,
I have a P4 3.06 w/ HT and HT is enabled and it shows up as two cpus in /proc/cpuinfo on redhat with the 2.4.20 kernel, but when I run gentoo it only shows up as once cpu. I have recompiled the kernel with acpi, cpu enumeration and smp but still no dice. It only shows up as once cpu. Does anyone have any experiece with this? I am trying to get it to work on 2.4.20-gentoo-r5.

from the help for CONFIG_ACPI_HT_ONLY:
In this configuration, ACPI defaults to off. It must be enabled
on the command-line with the "acpismp=force" option.
did you enable that?
ie for lilo add append="acpismp=force"
it refused to work for me untill I set that |

oh and kernel compile times for me:
with ht disabled:
real 9m6.293s
user 7m11.840s
sys 0m28.290s
enabled (using -j4):
real 5m47.689s
user 10m7.820s
sys 0m34.040s
3 mins chopped of it is quite nice 
similar(ish) stuff was running each time |
