Hi,
After upgrade to intel-xorg-video 2.21.4 driver, (Intel 945GM chipset) xserver
1.12.4 crash repeatingly
with sna enabled in xorg.conf.
A workaround i found is to fall back on "uxa" until the issue is resolve in
upstream. Backtrace:

[ 596.656]
Fatal server error:
[ 596.656] Caught signal 7 (Bus error). Server aborting
[ 596.656]

Please consult the The X.Org Foundation support
at http://wiki.x.org
for help.
[ 596.656] Please also check the log file at "/var/log/Xorg.0.log" for
additional information.
Can this bug please be checked by a upstream maintainer? I believe even with
--disable-composite compile
time option the xserver experiment severe bus errors.
xserver config:
./configure --prefix=/usr/local --disable-composite --enable-dri --enable-dri2
--enable-libdrm --enable-xorg --disable-debug --disable-maintainer-mode
--disable-ipv6 --localstatedir=/var --sysconfdir=/etc

Etienne
