Hello all. |
| 2 |
|

I've done a fair amount of research in order to try and solve the issue |
| 4 |
of my HyperThreading not getting enabled. I, however, have not gotten |
| 5 |
anywhere with it. |
| 6 |
|
| 7 |
I've got a 3.0GHz P4 with HyperThreading (Intel 531 processor for those |
| 8 |
of you who know of the Intel Processor Numbers) - kernel 2.6.13. I've |
| 9 |
enabled SMP and the HT scheduling option in the kernel config along with |
| 10 |
ACPI as I was told that it's a requirement in order to get HT to work. |
| 11 |
Yes, HT is enabled in BIOS. After compiling, installing, rebooting, etc, |
| 12 |
I don't see any changes. This is what /proc/cpuinfo shows: |
| 13 |

I've been reading about CPU Enumeration something-or-other but I've |
| 40 |
gathered that that option has been removed from the menus since the |
| 41 |
earlier 2.6 kernels. I'm not sure what bearing it would have on my |
| 42 |
current situation. I did recall that I had ACPI turned off in BIOS which |
| 43 |
logically should be on for the kernel to get any hardware backing but |
| 44 |
enabling it caused my keyboard to work up until a few seconds after the |
| 45 |
login prompt comes up. After that, it locks up (LEDs don't toggle). |
| 46 |
Everything else appears to work but I have to hard reboot the system. |
| 47 |
I've since turned ACPI support off in BIOS. A related power management |
| 48 |
issue that I should mention is that I used to use APM on my old mobo and |
| 49 |
with no other sub options enabled, it would cause my system to auto |
| 50 |
power off at the end of runlevel 0. Neither APM nor ACPI does this for |
| 51 |
me now (I assume because APM isn't used and ACPI is off and a lil |
| 52 |
misconfigged on my end, it would seem). |
| 53 |
|
| 54 |
Something tells me that all of this is related somehow. |
| 55 |
|
| 56 |
Anyway, any help would be greatly appreciated :) I seem to be having a |
| 57 |
rather unique experience as I've read several accounts of HT issues but |
| 58 |
all ended up resolved much easier than this has been going. |

Other information I know that I'll be asked for: |
| 61 |
|
| 62 |
Intel 865PE Northbridge |
| 63 |
Intel ICH5 Southbridge |
| 64 |
Latest BIOS |
| 65 |
correct memory installation |

Thanks! |
