Hi, I wanted to try 2.6.11-mm2 for the low latency/realtime lsm stuff and I've run into a severe problem.
When I try to start X, my machine reboots. The screen goes dark as usual when setting the video mode, but then I get a beep and I'm greeted with the BIOS boot messages. This happened 4/5 times i've tried, and once the video mode was actually set (at least I saw the usual X b/w pattern with some random framebuffer garbage), the machine didn't reboot but after that nothing happened. My keyboard was still responsive (ie NumLock LED would still go on/off), but i could neither kill X with CTRL-ALT-BACKSPACE nor could i switch back to console, so I ended up pressing reset. After the crashes I booted with a rescue CD to examine the logs, but I could not find any obvious errors. Everything works nicely on 2.6.10 and earlier kernels. I'm in the process of building 2.6.11.2 to see if the crash occurs there. Here is some info on my system: I've got an Athlon 1000C on a VIA KT133 chipset and a Radeon 7200 (the original Radeon with 32MB SDR RAM). I'm running Debian/sid. homer:/home/chrissi# X -version X: warning; /dev/dri has unusual mode (not 755) or is not a directory.
