Linux 2.6.38 power problems found!

Post by AlbertP » Sun Jun 26, 2011 9:27 am

Hello,

The Linux 2.6.38 power regression has just been found.

http://www.phoronix.com/scan.php?page=n ... &px=OTYwMQ

It might still take some time to get an update in Mint, but at least the core problem has been traced down.

From reading the article it sounds like he has found an appropriate "work-around" patch that should take care of the problem for anyone that installs a distro with kernel's .38, .39 and the newer 3.0 that is coming in the fall...That is great news...although he does sadly point out that there probably won't be a general fix (i guess he means from the actual kernel developers) for brand new clean installs of a system until kernel 3.1 or LATER! :?

Doesn't sound like he has too much faith in the kernel developers to get a true fix for it on their own that quickly :roll:

I sincerely hope his fix patch works...sure could use it...that power regression problem has prevented me from installing ANY distro with a kernel later then .37 on my home laptop which is my desktop and main computer...

Anyway..really good news and thanks for reporting it here and bringing our attention to it :D

I hope that it will get backported from 3.1 to 3.0, 2.6.39 and 2.6.38.

Yes, just installed Mint 10 instead of Mint 11 on and old laptop because of that. If an update/patch could fix the problem I would install Mint 11!

Installing 2.6.37 with Kendall's how-to is as easy as eating cake. And all power problems are solved.
You can set 2.6.37 as the default kernel in the Startup Manager.

Interesting :)
Could you supply a link to where the how to is posted..i might want to consider using it...

I think i would try the new "patch" first when it's ready...but kendall's solution might be useful for me in case for some reason this new patch we are discussing here doesn't work for me (though in the article it sure sounds like he feels it should work for everyone)...

Here's the link: http://forums.linuxmint.com/viewtopic.php?f=42&t=40185

It will add 2.6.37 as 'Older Linux versions' to the Grub boot menu.

That's nice, but honestly I wonder why they waited till now to actually track the regression the proper way. At the risk of talking out of my ass, that's the first thing I would have done. Maybe the equipment was too expensive to resort to immediately.
