Hello,

when I run the starwars hack from xscreensaver, Xorg freezes. The rest of the system is working, however, the console is locked forever. I was able to login remotely, but gdb Xorg crashed and killing X had no effect, even
did not kill X. top showed X is eating 100% of the CPU, and that almost
all of it is spent in the kernel.

Sounds like a GPU lockup. It's most likely an issue in the Mesa driver
in libgl1-mesa-dri. Please provide the full Xorg.0.log.

Here it is.

Just if you are interrested, I'm able to get a strace by attaching Xorg before the freeze. At the end, it contains repeated

ioctl(7, 0x6444, 0) = EBUSY

and SIGALRMs

Should I get a full strace?
