Description KKnull 2009-11-09 09:27:40 UTC 
hi,
I don't know if this bug is related to xorg or radeon driver,
very often xorg crashes when I type something and then press enter...
xserver 1.6 was not affected.

Any chance you could install the xserver and driver debugging symbols and get a real backtrace with gdb?

Also, in the future, please attach files rather than linking to external sources.

ok, I'm trying to debug X, gdb stops the execution very often, here are some backtraces:

backtrace 3
Comment 6 Michel Dänzer 2009-11-14 08:51:24 UTC 
The backtraces are missing information about which signal it is, but most likely it's SIGPIPE which is normal and handled by the X server. Enter

handle SIGPIPE nostop noprint

at the gdb prompt to make gdb ignore it.
Comment 7 KKnull 2009-11-14 09:03:51 UTC 
yeah,
they were SIGPIPE. Now I was able to crash the server (with SIGABORT I think)
Backtrace is attached
