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. Users ought to be given the option of re-enabling it on the 4G, but be given an appropriate caution about lack of vendor support for this configuration.

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.

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. Fair enough. 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.
