I think I would try updating your usb stick's kernel with 8-stable and rebuild it. I'm wondering if someone who made the stick image turned off SMP to make i fit on small sticks (above is 7.2-stable, not the 8 on a stick). I see HTT in your CPUs features, but I wonder what that's based on. What if the BIOS supports hyperthreading but the cpu doesn't? (there were p4 processors sold before hyperthreading came out, I know, I bought one. 8o) You might try finding a cpu diagnostic tool that describes the cpu in great detail, like from download.com, etc. You might also go to Intel's site and lookup the id 0xf29 and see if Intel says it actually supports hyperthreading. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

Hello have you looked to your /etc/rc.conf set to the following by adding: powerd_enable=YES power_flag'-i 85 -r 60 -p 100 or Now you can also modify this file: /etc/sysctl.conf or /boot/loader.conf (CPU Frequency) debug.cpufreq.lowest=600 To test live in your terminal you can set it with this command: sysctl debug.cpufreq.lowest=600 Now you can set it to 1200 but I would recommend 100 at a time for testing.

I don't know. Since last time, I've upgraded the bios to the latest
(A03) and reset bios to default values - but the problem is still there.
According to the specs, a SX260 supports all Pentium 4 cpus with 400
MHz and 533 MHz FSB (front side bus).
Yes, this is your problem, regarding speed anyway. I only picked up on
this because this year we bought 2 used intel mobos on eBay; a D845GBV
with a 2GHz P4 (also 400/533 MHz FSB with similar 845 chips to yours)
and the other a D865GLC with a 2.6GHz HTT P4 (400/533/800 MHz FSB).
Only the D865GLC 800MHz FSB board takes the 2.6GHz HTT P4, shown as
'2.60C GHz' in the board manual and also on this page:
http://www.intel.com/support/processors/pentium4/sb/CS-011987.htm
Our older 400/533 FSB board only takes a non-HTT P4 using 400MHZ FSB,
('2.60 GHz' without the 'C'), though it only has a 2GHz non-HTT CPU.
After a looong time hunting through fluff and bumph from various angles
and searches on the intel site (argh!), I finally found:
http://processorfinder.intel.com/List.aspx?ProcFam=483
Where there are several 478-pin 2.60GHz P4s with 512MB L2 cache, eg:
http://processorfinder.intel.com/details.aspx?sSpec=SL6WS (800MHz FSB)
http://processorfinder.intel.com/details.aspx?sSpec=SL6QR (400MHz FSB)
but all of the HTT 2.6GHz ones require 800MHz FSB, so I guess this is
why its set to run at half speed by your board? Perhaps the SX270 you
mentioned having taken this CPU out of, supported up to 800MHz FSB?
Something set that way in BIOS? What does 'sysctl dev.cpu' say?
The only setting in bios related to cpu speed are
normal and comaptible. I've tried both - doesn't make a difference.
Now sysctl.dev.cpu says:
r...@kg-work2# sysctl dev.cpu

dev.cpu.0.freq_levels: 1295/-1 1133/-1 971/-1 809/-1 647/-1 485/-1 323/-1
Yeah, just p4tcc thermal throttling, no EST speedstep control on these;
powerd could save you some heat but not much less power use, I gather.

Not, I didn't make one that evening. There is one over ther now. :-)
I suppose you have HTT disabled in BIOS?
Yes, I had, it is enabled now.
Well I don't imagine running at half speed with HTT is going to be as
quick as full speed without .. and I'll guess further that this is what
the 'non-uniform processors' message is likely about. You may find that
putting a faster non-HTT P4 in it, maybe up to 2.8GHz would go better,
or that search tool shows some 3.06GHz and a 2.40A GHz HTT @533MHz FSB.

WARNING: Using suboptimal topology. ioapic0: Changing APIC ID to 1 ioapic0 Version 2.0 irqs 0-23 on motherboard kbd1 at kbdmux0 Full demsg output on the FreeBSD page[2] for this machine. Only spotted a verbose dmesg for 7.2-STABLE there, not for 8.0? Why does FreeBSD think that this machine has non-unform processors? Ok, the Pentium 4 in it can proably do hyperthreading, but that isn't much to talk about. I suppose you have HTT disabled in BIOS? What excatly is non-unform here? I don't know, but suspect the detected half CPU speed may be a clue?
