Comment 214 for bug 355155

I am beginning to believe this an overclock or a over heating issue.

My system(s) are identical images. I have a Phenom 940 Black that has run stable for 4 months. When a customer defaulted on a 955 Phenom chassis with the same specs (except the 955) I kept it and imaged the 940 to the same exact drive on the 955

Both ran great for 1 month.

Then I got into overclocking. The 955 has handled everything I have thrown at it and as never frozen. It also maintains a very good core temp of 44

Since an Update Manager update one week ago, the 940 has done nothing but freeze and/or reboot with no discernible pattern. It could happen in 45 minutes, 4 hours or 10 hours. It could happen with only term running 20 apps running or nothing at all sitting completely idle.

Until today. I turned off the overclock on this 940 and have seen stable system again. My core temp with the over clock on was a wierd one. Using gKrellM I would see core 1 and 3 at 41-42 but core 2 at 51-53. Overclock off now I see all core temps at 39-40

The only other thing I can add to this is that I am getting the gdm_slave_xioerror_handler in Xorg after a freeze/reboot.

And that since that same update a week ago, on both machines, neither monitors go into a dark mode with inactivity like they used to.

I am running kernel:

2.6.29.4-candela #1 SMP Tue May 26 22:26:20 CDT 2009 x86_64 GNU/Linux

I stay completely updated.

In both machines I have the same make and model nVidia 9500 GT running driver 185.18.14

Hoping some of this helps....
