Hi
I have installed FreeBSD 6.1-RELEASE on my Compaq Presario 2656AU
laptop, but it occasionally hangs. I traced the problem to powerd so I
made a script that kept changing the clock rate by setting the sysctl
dev.cpu.0.freq. This script normally makes the computer hang within 10
seconds or so.
I then added a few printf's here and there which have let me to
believe that the problem is somewhere in
sys/dev/acpica/acpi_throttle.c, acpi_thr_set
It only prints the first letter of a printf just after the line
THR_SET_REG(sc->cpu_p_cnt, p_cnt);
The problem happens with and without cpufreq.ko loaded. The kernel is GENERIC.
Any Ideas?
Cheers,
Tim

Sam Leffler noticed this on his nx6125 last December and I also
found the same problem on my nx6125 in early February. It looks
like there's a race condition in the BIOS code.
>Any Ideas?
My current solution is to manually change the speed using sysctl.
This doesn't seem to trigger the problem quite as often (though your
laptop seems far more sensitive than mine). I would also be interested
in any real solutions.

Glebius@ (CCed) sent me a patch against 6-STABLE which solves the
problem. However, I don't know if the patch was committed.

dmesg would be a good start. Is there some cpufreq driver running
besides acpi_throttle? Add hint.acpi_throttle.0.disabled="1" in
loader.conf, reboot, and then retry your test.
My guess is acpi_throttle is just a wrapper around p4-tcc on your system.

I'll be away from FreeBSD mail until October. Please direct questions
to the lists and not to me directly.
Thanks,

dmesg with and without cpufreq.ko loaded:
http://www.studentergaarden.dk/~tim/FreeBSD/dmesg_cpufreq.txt
http://www.studentergaarden.dk/~tim/FreeBSD/dmesg.txt
If I set hint.acpi_throttle.0.disabled=1 i need to have cpufreq.ko
loaded to be able to change the frequency, but in this case I have not
been able to get it to hang. With acpi_throttle enabled it hangs both
with and without cpufreq.ko loaded.
Another interesting thing is that different configurations lists
different freq_leves.
acpi_throttle:
dev.cpu.0.freq_levels: 1799/-1 1574/-1 1349/-1 1124/-1 899/-1 674/-1 449/-1 224/
-1
acpi_throttle and cpufreq:
dev.cpu.0.freq_levels: 1800/25000 1600/20700 1400/18112 1200/15525
1000/12937 800/8600 700/7525 600/6450 500/5375 400/4300 300/3225
200/2150 100/1075
cpufreq:
dev.cpu.0.freq_levels: 1791/25000 1592/20700 796/8600
(I think these are the values used in Windows, where it doesn't hang)
One last thing. If I load cpufreq after having changed the cpufreq via
acpi_throttle the values gets weird:
dev.cpu.0.freq_levels: 7362/25000 6544/20700 5726/18112 4908/15525
4090/12937 3272/8600 2863/7525 2454/6450 2045/5375 1636/4300 1227/3225
818/2150 409/1075

If that was a patch that was required for merging the em(4) changes,
then the answer is "yes". It was merged to STABLE.

Gleb, thanks for the info!
Then I may suggest Tim to upgrade to the lastest -STABLE to avoid the

You shouldn't delete the quoting. ;-)
So, those patches (needed to _merge_ the em(4) changes) are really for
the acpi subsystem. I had a freezing notebook after updating to
6.1-RELEASE and found out that the recent acpi changes are to blame.

Can you point me to this commit? I browsed the sys/dev/acpica and
sys/i386/acpica tree and fail to see a commit by glebius@.

I'm running current on an IBM ThinkPad T43 and I'm not sure I have a problem,
but something odd seems to be going on.
I have a 2.0 GHz Pentium-M which I believe is 760. I believe it's one IBM has
not released information on the EST specs.
If I do NOT have cpufreq loaded, I see:
dev.cpu.0.freq_levels: 2000/27000 1750/23625 1600/22600 1400/19775 1333/19666
1166/17207 1066/16733 932/14641 800/13800 700/12075 600/10350 500/8625
400/6900 300/5175 200/3450 100/1725
If I load cpufreq I see:
dev.cpu.0.freq_levels: 1500/-1 1312/-1 1200/-1 1050/-1 1000/-1 875/-1 800/-1
700/-1 600/-1 525/-1 450/-1 375/-1 300/-1 225/-1 150/-1 75/-1
With cpufreq I report perf0, est0 and p4tcc0 in dmesg. Without loading cpufreq
I still see acpi_perf0 and acpi_throttle0.
This would lead me to believe that without cpufreq I am only seeing
throttling, but I see my clock speed decrease (x86info) which I did not expect
to see with pure throttling.
Am I better off when on battery to use cpufreq or not? Is there something to
tweak to get full 2GHz performance with EST?

This is it:

It doesn't fix any bugs in ACPI.

Ok, I agree. This is a patch to update the taskqueue api, not a bug in
ACPI.

Peter,
One think I have noticed is that some slower speeds available with P4TCC
throttling will cause the system to lock. This has always been the
case. On my T30 which was a P4-M at, the lowest speeds available with
P4TCC available was 75 or 100 MHz and setting my speed to either of the
two lowest values would lock the system. I patched powerd to prevent
either of these from being selected and everything worked form that
point.
That was a MUCH older version of powerd (at least from early last year)
and I no longer have the T30.
My new T43 seems to not have this problem. It runs flawlessly at all
speeds, whether I enable EST (cpufreq) or not. The system clearly does
better with cpufreq than without, but it falsely reports CPU speed with
cpufreq.

Also, I think that debug.cpufreq.lowest can be used to limit the low
speed and avoid the ones that cause hangs.

That, and if you find the problem driver, you can just disable it
individually. example:
hint.p4tcc.0.disabled="1"
If that doesn't work, try disabling acpi_throttle the same way.
Figuring out which cpufreq drivers are attached on your system would be
a good start (dmesg | grep cpu).
All other cpufreq drivers will continue to function just fine. That's
why the title of this message is misleading. cpufreq is a framework,
not a single driver. It's like saying "PCI makes my system hang".
