Comment 216 for bug 355155

"I will try the mainline kernel (the .30) and let you know. If it fails (when) I will report back here and install your .28 kernel and see how that does."

I'm sorry, I don't think I'm going to be much help with the issue of freezing to black. I installed the 2.6.29-5 mainline generic kernel and I messed-up my system somehow. I think it must have been while I was trying to roll-back my x installation. In any case, my xorg.log says that my radeon driver is failing to open DRM.

Now my system is showing symptoms sounding very similar to those of Sir Romanov. It's very sluggish, even window scrolling in Firefox is choppy - and forget watching a video, even in a little screen (streamed). My temps are up, and xorg is using a lot of processor time (10 - 20% with only a couple of windows open). If I try to stream a video, the system will become so sluggish that the desktop will slow to a stop, with little or no input accepted or output given - even the plasma cpu monitor will freeze and the graphical volume slider will refuse to work.

This is completely unlike my experience of the system freezing to black, which happens suddenly, unexpectedly, and without apparent change in system temp. If you've read any of my posts, here and elsewhere, you know that I did experience symptoms similar to what I'm experiencing now, ie. freezing of a program with a rapid rise in temperature and a return to normality when the offending program is terminated, but those freezing programs were uncommon on my system.

I doubt it is the .29-5 kernel, since I have read of many others using this kernel without issues - but it could be, I suppose. I'll boot into another kernel and see...

So far I have had no freezes to black today. Oh, I always have desktop effects disabled.
