How about cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed and echo 1700000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed Did you use vanilla 2.6.6 or 2.6.6 mm kernel?

(In 2.6.5 vanilla from kernel.org doesn't work too)
Do you use speedstep-ich or p4-clockmod? Can you please post lsmod and dmesg?

Created attachment 3105 [details] dmesg kernel with debug speedstep patch Here is my dmesg from kernel with this patch to kernel: http://bugme.osdl.org/attachment.cgi?id=3089&action=view nbdebian linux # patch -p1 < /root/zaloha/kernel-patches/speedstep-debug patching file arch/i386/kernel/cpu/cpufreq/speedstep-lib.c nbdebian linux # (in /usr/src/linux, here i have sources for my 2.6.6 kernel, before this i use make clean command) But i can't see any differences.
Please de-select p4-clockmod from your kernel config, it doesn't do you any good anyway, AFAICS. Please de-selct speedstep-ich from your kernel config also, as your notebook does not contain an ICH southbridge. Please select the ACPI P-States cpufreq driver in your kernel config, though, as that one likely will offer you frequency and voltage scaling -- and it will likely report correct frequencies.
Created attachment 3137 [details] my kernel config I recompiled my kernel same config without p4-clockmod and speedstep-ich. But same result. nbdebian ailas $ grep -i mhz /proc/cpuinfo cpu MHz : 2358.716
can you please post a cat /sys/devices/system/cpu/cpu0/cpufreq/* and -- if the file exists -- cat /proc/acpi/processor/*/performance
New info: Now, i have much faster responses in X. i try recompile kernel again, without CONFIG_X86_PM_TIMER (in ACPI), CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI and CONFIG_X86_SPEEDSTEP_SMI. If i cat /proc/cpuinfo i get right frequency cpu MHz : 1700.384. i start /etc/init.d/cpufreqd, while ac is on, freq is 1.7G it's ok, while i unplug power freq goes down to 1.2G (it's ok, this i have set in /etc/cpufreqd.cond based on cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies which show me 1700000 1200000). In terminal it's ok, but if i'm in X, seems to crash my keyboard (sometime whole system) Info what you want: (i wrote simple script for better info) nbdebian cpufreq $ pwd /sys/devices/system/cpu/cpu0/cpufreq nbdebian cpufreq $ for i in `ls *`;do echo -n "$i: "; cat $i;done cpuinfo_max_freq: 1700000 cpuinfo_min_freq: 1200000 scaling_available_frequencies: 1700000 1200000 scaling_available_governors: powersave userspace performance scaling_cur_freq: 1700000 scaling_driver: acpi-cpufreq scaling_governor: performance scaling_max_freq: 1700000 scaling_min_freq: 1200000 nbdebian CPU0 $ cat /proc/acpi/processor/CPU0/performance state count: 2 active state: P0 states: *P0: 1700 MHz, 20000 mW, 250 uS P1: 1200 MHz, 10000 mW, 250 uS (i have only CPU0)
Thanks for the information. It seems that the original problem (wrong cpu_khz) is solved; with regard to the keyboard or system lockups you're experiencing: are these happening right when the frequency is changed, or does this happen independent of frequency switching?
I make some tests: If i run with ac in, there is no problem. In console without ac, all ok. 1.7G and 1.2G, no matter, seems to work. In X (XFree86 Version 4.3.0.1 (Debian 4.3.0.dfsg.1-4) and Gnome (2.6) sawfish wm, i have problem. If i try start my session (from login gdm screen) without ac adapter, system hang up after draw wallpaper with color links (vertical). I must force unplug power. If i have started session and unplug ac, after few seconds screen stay "freezed" and i can move only mouse - but i can't click anywhere and in terminal i have "tail -f /var/log/kern.log", but if i push power button, i can't see any change like "system goes down....". Screen is like screenshot. Sometimes system correctly goes down, sometime freeze.
can you cat /proc/acpi/processor/CPU0/performance when running on battery, please? Also, what kernel are you (currently) running?
cat /proc/acpi/processor/CPU0/performance state count: 2 active state: P1 states: P0: 1700 MHz, 20000 mW, 250 uS *P1: 1200 MHz, 10000 mW, 250 uS I'm running kernel 2.6.6_8_mm5-debug, version from Comment #12. (-debug in name because is still with patch from comment #7)
Let me summarize: if booting on AC, speed is detected correctly now, everything works fine. if booting on battery power, speed is detected correctly. Random errors not related to switching frequencies. To rule out any cpufreq-related errors: could you re-compile with CONFIG_CPUFREQ set to "n", and test on battery? If the errors continue, these are _not_ related to cpufreq...
Hi. No. Everything depends on cpufreqd now. I have disabled autostart cpufreqd on boot in rc script. If i unplug AC and cpufreqd is not started, is all ok. If i do /etc/init.d/cpufreqd start: AC off in terminal - no problem. AC off in X, system freeze after 1s (few ms). If i unplug power before i'm in X, gdm start ok, and after login hangs.
OK, I see. Obviously, the ACPI cpufreq driver doesn't like doing dynamic frequency switching on your notebook. Will look closer at the problem this evening.

Same result. After recompile i try in X terminal start cpufreqd. nbdebian ailas # /etc/init.d/cpufreqd start Starting CPU Frequency daemon: cpufreqd. And X freeze, keyboard seems death too.Only power button react, after i push power button, system shutdown in 2-3 minutes (it is too long).
Strange. I'd like to zero in on this X freeze... can you re-compile with AGP and DRI/DRM disabled, and explicitely disable these features in /etc/X11/xorg.conf or /etc/X11/XFree86.conf, depending on your X package...
I try just turn off Load "dri" module in /etc/X11/XF86Config-4 and everything seems to be ok now. I'm running cpufreqd while i'm in X with ac or without ac correctly. Much Thanks for all! (what can i do now? i don't know where is the problem)
The problem (probably) lies somewhere in the 0000:01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY and the DRI/DRM code which utilizes the advanced features of this video card. However, it is a really really strange bug. To rule a small bug out John Stultz discovered lately, could you try out again with dri enabled, but these three patches applied to your kernel, please? http://lkml.org/lkml/diff/2004/6/15/17/1 http://lkml.org/lkml/diff/2004/6/15/16/1 http://lkml.org/lkml/diff/2004/6/15/18/1
nbdebian linux # patch -p1 < /root/zaloha/kernel-patches/1 patching file arch/i386/lib/delay.c patch unexpectedly ends in middle of line is this ok?
Same result, i try start cpufreqd, X (keyboard?) freeze. Button power off working.
Let me summarize: - the original problem is solved - the video (and, partly, other parts of X) locks up if the _CPU_ frequency is changed _and_ the DRI/DRM driver is active. CPU frequency changes with DRI/DRM disabled works fine, DRI/DRM works fine if CPU frequency stays the same... - does anybody have an idea how the CPU frequency might affect the radeon DRI/DRM driver, given the FSB stays the same, and the "delay()" functions still work properly even after frequency transitions as loops_per_jiffy is adjusted (also the per-CPU copy of it). - because of this, I'll try to re-assign this bug to DRI/DRM -- if they don't like this bug, please close this bug, OK?
Yes, this is exactly the problem now. OK.
I've no ideas on this either, there should be nothing cpufreq should affect in the dri/drm driver, I'm thinking the X server may be doing something bad and XFree86 4.3 in Debian is pretty old... I might see if I can reproduce this on my laptop when I get a DRM working on my pciexpress graphics card...
I have the exact same problem with DRI/DRM enabled, the video in AGP mode and cpufreq changing cpu clock speeds. Everything runs fine so long as the cpu frequency stays at one setting. Setup: HP Omnibook xt6200 Gentoo Linux 2005.x Kernel: 2.6.11-gentoo-r11 CPU: Intel(R) Pentium(R) 4 Mobile CPU 2.00GHz (It has the same low clock speed of 1.2GHz when in "low power mode".)
I did find that changing to a console virtual terminal (not using a frame buffer), changing the clock speed and then flipping back over to X does work flawlessly in both directions (high->low, low->high). When doing this (even without changing the clock), agpgart reports putting the device into AGP Nx mode each time.
It looks like this only occurs with the Radeon in >1x mode while doing FID/VID changes. Both 2x and 4x modes will lockup the system during a FID/VID but 1x mode will not. To make it work for even 1x AGP mode, enable CONFIG_I2C, CONFIG_I2C_ALGOBIT, CONFIG_I2C_ALI1535 as compiled in options. I've tested this with using both the ondemand governor and forcing a FID/VID by setting the P-state in /proc/acpi/cpu/CPU#/performance. I'm still not sure why having the AGP clock at 2x or 4x locks up though.
Sorry, i can't test it. I changed notebook model and vendor, so i can't help with report in future. Thanks -- sign: Josef Rysanek (ailas) <ailas@ailas.net> www: http://www.ailas.net/ -- Odchozi zprava neobsahuje viry, protoze nepouzivam MS Windows
I think this can be closed. I have a Radeon 9600 mobile, no lockups on switching laptop power mode and I'm using AGP 4x mode always.
Yes, thank you.
