Fwd: [Bug 92111] Power regression from 3.17 to 3.18 and 3.19

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

The _OSI("Darwin") support seems to break CPU power management for Attila.

Is there anything we can possibly do about that?

Strange result, but git bisect shows this commit to be the first bad:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7bc5a2bad0b8d9d1ac9f7b8b33150e4ddf197334

I guess this acpi change results that CPU is not allowed to go deeper states
than pc3. I will do a build of 3.18 reverting this commit to make sure this was
the problem.

I will enclose a bisect log soon.
