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 #1 0x00000000004692ec in _XSERVTransSocketWritev (ciptr=<value optimized out>, buf=<value optimized out>, size=<value optimized out>) at /usr/include/X11/Xtrans/Xtranssock.c:2174 #2 0x00000000004617dd in FlushClient (who=0x5aa9630, oc=0x5661750, __extraBuf=0x0, extraCount=0) at io.c:937 #3 0x0000000000462051 in FlushAllOutput () at io.c:681 #4 0x0000000000430373 in Dispatch () at dispatch.c:402 #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.
