Bug#559578: Fwd: Bug#559578: eeepc-acpi-scripts: EeePC 701 freezes with garbled screen while booting
Hi Corentin It looks like it's not just my 701 which has problems with SHE. Given that Asus don't support it on the pre-installed OS, I think we should disable it for the 701. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=559578.

If by we, you mean Debian, and by disable you mean disable by default, then I agree. However, I don't believe it should be disabled upstream. I have used SHE successfully on the 4G for several weeks. Although SHE became suspect when I experienced some lockups, after running for a few days with SHE disabled, I still get occasional lockups, so I don't no longer think SHE is the cause.

Ben I think the kernel should disable SHE by default on the 701 models. I don't mind if it provides a force_cpufv option with an appropriate warning. The 701 models aren't shipped with any way to control the SHE. It is a form of overclocking which is not supported by the vendor. On the other models, SHE is a marketed feature which users will expect to work reliably. We should treat these cases differently in the kernel. I don't think it should be left to userspace to get this right. There are other distributions than debian :-). I've seen at least one desktop applet which controls SHE. I expect it has a similar option to toggle SHE automatically when switching between mains and battery power. If we change the kernel, it will affect everyone. The ABI doc for eeepc-laptop doesn't say writing to cpufv may break, so we need _some_ change to the kernel sources :). I think it's better to fix this in the code and not just add disclaimers in the documentation. Alan -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.

Reportedly http://groups.google.com/group/linux.debian.bugs.dist/msg/9805f22bc6b8bbda. Another report says it happens only when booting in single user mode, and not every time. I can't reproduce it myself, even though it's happened to me in the past, both from writing to that file manually, and from the default configuration of eeepc-acpi-scripts. I _can_ still reproduce the strange hissing noise in performance mode. If I repeatedly plug and unplug the power adaptor with eeepc-acpi-scripts installed (triggering the switch between performance and normal), I see various kernel messages. These are the kernel init messages for the webcam and cardreader, suggesting that they are disappearing and re-appearing. I wasn't able to reproduce it without eeepc-acpi-scripts (either by plugging / unplugging repeatedly, or by toggling the value of cpufv in a scripted loop, or by both at the same time). I don't have my 701 right now, so I can't test, is there anything in dmesg or is it only a bad hardware freeze ? Apparently it's just a freeze: Indeed it sounds like 559578, and before proceeding further, though garbled, I have compared the blurred lines to a regular boot, and it turns out the final words before freezing are: Wed Dec 9 09:34:02 2009: Loading EeePC support modules...done. Wed Dec 9 09:34:02 2009: Setting super hybrid engine according to configuration...(AC)...done. http://groups.google.com/group/linux.debian.bugs.dist/browse_thread/thread/d3f0716684bbadd8 Anyway, if we disable it for 701, how can we detect that this is a 701 ? using dmi matching ? when only 2 modes are available ? Thanks, I would use a DMI match (product name 701). Hopefully that is distinct from the 701SD, which is marketed with SHE. I know the 900A has a distinct product name, so it seems likely.

By the way, if you're referring to the same applet I'm thinking of, it is capable of using means other than cpufv to change speed (by access to certain registers directly, i think) so fixing cpufv doesn't adequately protect users of that applet.

Hello! I can confirm this bug. However it 's not a problem with acpi scripts, but rather a bug in the kernel [module]. I experience exactly the same problem when I manually switch performance settings from 'normal' (default), to 'performance': echo 0 /sys/devices/platform/eeepc/cpufv My Eee PC is also 701 4G (originally shipped with MS Windows XP) and currently has Karmic Koala with 2.6.31-15-generic kernel installed. Maybe I should try a different kernel, or try to load a specific module or whatever else... Actually I would prefer to have a 'powersave' mode rather than performance. However only 0 and 1 are reported in available_cpufv. BTW Windows was able to downgrade performance when battery was close to discharge. But maybe it was a hardware feature activated specially for an operating system which is known to be a speed hog :) Sincerely, Alexey Morozov -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.

Interesting. That'd be when it switches, or tries to switch, to high-speed mode. AFAIK there is (officially) _no_ high-speed mode on the 701. It's a 900 MHz Celeron _permanently_ underclocked to 630 MHz. I remember there were some kernel module hacks to run it at 900 MHz nevertheless, but this was IIRC quite unreliable so I stopped using it after some tests. Can't remember the details what was bad about them, but I still know it caused far less problems (especially not reliably reproducable problems) than this one. I wonder if this could be BIOS-related; listing both known-good and known-bad BIOS revisions may be useful since we can then blacklist (or whitelist?) and encourage upgrades, or possibly downgrades, where appropriate. dmidecode says: [...] BIOS Information Vendor: American Megatrends Inc. Version: 0910 Release Date: 03/03/2008 [...] ftp://ftp.asus.com.tw/pub/asus/EeePC/EeePC4G%28701%29/ should be right for what you have.

However, they did build into the first model the ability to use it. They just didn't give any access to that feature when they shipped it.

I remember there were some kernel module hacks to run it at 900 MHz We don't support it via a hack. The eeepc_laptop module which is a standard part of the kernel now supports access to S.H.E. via /sys/devices/platform/eeepc/cpufv for all models, whether or not Asus lists support. nevertheless, but this was IIRC quite unreliable so I stopped using it after some tests. Can't remember the details what was bad about them, but I still know it caused far less problems (especially not reliably reproducable problems) than this one. Given that Asus lists no support for this, perhaps we should patch eeepc-acpi-scripts to detect model 701 and disable the setting by default, only enabling it for all other models. I have a model 4G and have been using S.H.E. performance mode while on AC for some time. I occasionally suffer lockups, but that could just as well be due to the still immature support for KMS as anything else. I'll try for a week to do without S.H.E. and see if the lockups cease.

Ok, I now have 1.1.3 installed and the following setting cause the problem: PWR_CLOCK_AC=0 PWR_CLOCK_BATTERY=2 as well as the default values (both empty) of course. The following settings work fine and make the problem disappear: PWR_CLOCK_AC=1 PWR_CLOCK_BATTERY=2 PWR_CLOCK_AC=2 PWR_CLOCK_BATTERY=2 So to be on the save side, I suggest for the EeePC 4G (aka 701) to either disable SHE or use the 1+2 setting as default. I'm currently not at home. When I'm back at home, I'll upgrade the BIOS from 0901 to 1302 to see if the problem still persists. If it doesn't persist, a BIOS version check could be done to check for BIOS versions below 1302 to enable safe settings.
