--- Comment #6 from Sergey Kondakov <virtuousfox at gmail.com> 2010-12-17 12:36:00 PST ---
after recent update my X also started to segfault with same message in dmesg.
xorg-server is 1.9.3;
mesa, libdrm, xf86-video-ati are most recent git;
kernel is on SMP x86_64;
card is discrete "ATI Technologies Inc Mobility Radeon X2300"/RV515 on r300g

backtrace from kdm.log:
"Errors from xkbcomp are not fatal to the X server

Segmentation fault at address 0x10

Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting"

after writing the above and forgeting to post it from another machine i found
out that offender is not xf86-video-ati, but, in fact,
xf86-input-evdev- with downgrading to xf86-input-evdev-2.5 there are
no more segfaults (it were 100% segfaulting if i would touch a touchpad).
i can't say if dmesg error message have something to do with it but it's
definitely were poping out in log right before X death every time.
