Description Jure Repinc 2010-11-27 08:54:54 UTC

Hardware: ATI Mobility Radeon HD 5470
Software:
KDE SC 4.5.3 (with desktop effects enalbed of course)
Linux 2.6.37-RC3
Xorg Server 1.9.2.901
Mesa, libdrm, xf86-vide-ati all from git

While using the open source, radeon driver the system is randomly freezing. I can't determine one use case when it happens. After it freezes the SSH to the system is still operational, so it looks like only X freezes. I can't see any 100% CPU usage in a frozen system.

I also checked dmesg and I can't see any message when this happens. Xorg.0.log also doesn't show any crash. I have once attached with GDB to X process before the freeze happened and the only thing I could get out of it was:

Program received signal SIGPIPE, Broken pipe.
0x00000036188ca301 in writev () from /lib/libc.so.6
(gdb) where
#0  0x00000036188ca301 in writev () from /lib/libc.so.6

#5  0x00000000004249ed in main (argc=10, argv=<value optimized out>, envp=<value optimized out>) at main.c:291

I don't know where else too look for more useful info on what happened.
