[Bug 817528] New: long-standing radeon driver issues - crashes and lock-ups

Prior to that, whilst 3D acceleration wasn't available, my systems otherwise ran fine. There was a brief moment for one release (may have been 11.1 or 11.2, I struggle to recall) where the improved radeon drivers provided working 3D and the outlook was bright, then around whatever release it was when KMS was introduced, 3D via Gallium became unstable, and things seem to have just got worse since. With a fresh default openSUSE install my Radeon 9600/9700 card seems to work fine, but after a few days there will be a lock-up. The screen briefly flashes blank and then everything comes back frozen, usually requing a Magic Keys reboot. Once this cycle begins it seems to accumulate and gets worse, with subsequent logins not lasting very long before it happens again. Ultimately, after fiddling for years with all sorts of Xorg.conf tweaks, nomodeset and other graphical settings, I've found the only way to stop this is to disable hardware acceleration in the 50-device.conf file. This has occurred both on my laptop with an ATI Mobility Radeon 9700 card (based on the 9600 series, RV350), and a totally different desktop with a Radeon 9600 AGP card. I'm no longer able to test on the latter because I finally conceded and replaced it with an nVidia but I can't do any such thing on the laptop. It's a shame because despite being very old the system works perfectly well in all other respects, but this disabling of hardware acceleration in the latest releases of openSUSE renders the system so sluggish it's barely usable, and I'm going to have to finally ditch this laptop if this issue can't be fixed. By default I'm using KDE either with or without compositing. I've contributed to various other bug reports and forum / ML discussions in the past, some which were marked as resolved or never went anywhere, but with every release I suffer roughly the same symptoms. What I've noticed in 12.3 is that it is often keyboard input that triggers the condition, either in a web browser text field or a basic text file, etc. Or maybe that's a consequence rather than a cause. On the most recent occasion today my usual procedure of Alt-SysRq REISUB couldn't even resolve the issue, and the screen gradually faded over the course of a minute to a pattern of rainbow vertical lines. I noticed a message on the subsequent cold/warm reboots about radeon problems. It seems like some accumulating memory problems in the graphics memory, but the same issue occurring on the desktop machine suggests this isn't just bad memory on one card. I'm attaching a piece of the var/log/messages file from today which may provide some clues. I've made a copy of today's xorg.0.log and xorg.0.log.old if you need those. I can't reproduce the issue on a reliable basis. If I enable hardware acceleration again via the 50-device.conf file I'll at best go a few days of stability before all hell breaks loose again. I cannot boot in failsafe mode because of the bug where it reaches target graphical interface and then hangs. I tried switching to vesa but it's extremely unstable and fbdev is so slow it's virtually unusable. Of course, the ATI proprietary driver for this generation of card was deprecated years ago so that's not an option either. I can't say for sure if this is a SUSE-specific issue. It's my main production machine with limited memory (1GB) so I don't want to play around installing other distros or virtual environments.
