Last 2 versions are broken.
Last 2 versions of Radeon drivers are broken. Previous versions (buit before February) were just fine.
Tested on HD5770 and...
1) Compressed textures aren't handled correctly now (or memory transfers are seriously broken). I can see textured surfaces with compressed textures are full of very specific block-based garbage. It has worked perfectly 2 releases ago though. Only February versions are broken.
2) After some time (some seconds to ~10 minutes) of mentioned 3D loads, GPU locks up. Kernel attempts to reset it and then reset fails. System locks up so hard that even die-hard Alt-SysRq keys are gone at this point and it locks up even before anything meaningful in kernel log could be written to disk. So there are no logs with crash.
Previous versions were fine in both compressed textures handling (I use libtxc-dxtn-s2tc0) - there was no garbage. And there was no any lockups even after hours of any 3D loads.
N.B. I'm using 3.8 RC5 and RC6 kernels. They were fine with pre-February versions.
I think most recent libdrm is busted on intel
been having major stability problems (monitor connected on VGA is very fuzzy with bad colours at X startup though DVI monitor is fine, and after 1-2hrs uptime the system starts thrashing badly) since 2/12 when the package was last updated, but they go away when I restart lightdm so I think it's an X issue. tried forcing stable versions of xorg-intel from other PPAs but that didn't do the trick; unfortunately when I try to force version of libdrm, synaptic claims I need to remove virtually every application on my system that depends on X, and I'd rather not go through that.
any word on how I can smoothly revert (I did an apt-get clean thinking I might have dpkg corruption so I don't have slightly older packages in my cache to use) or when you might have a fixed update?
managed to revert smoothly, but problem persists; maybe llvm is the issue?
solved synaptic issues by basically unmarking dependencies one-by-one (had to do a few of them simultaneously, e.g. wine and wine:i386, but I got it). however, the problem persists. I grabbed the debian version of llvm-3.2, as that's the only other oibaf package that updated around when I started experiencing these problems, and I couldn't find a more stable version in a ubuntu PPA. we'll see what this does...
Valve team fortress problem
in the past, TF2 worked using mesa 9.1 on a ubuntu 12.10... but i was busy for several weeks and now when trying again TF2 crashs on finishing loading the resources (3D related crash)
i also found that Killing floor game also crashes when loading the map (again 3D crash)
Does anyone using this drivers have the same problem? or i manage to break my system :)
