I can't find the other e-mail in which someone suggested using XAA
acceleration, but that seems to have worked so far. Thanks, all!
It doesn't work. It improves the time between two crashes, but does not
eliminate them. The only workaround that makes intel drivers stable atm is to
add Option "NoAccel" "true" into xorg.conf, but that kind of defeats the
purpose of having a supported, open source, 3D accelerated driver.
I have also set XAA instead of EXA, and it does slightly improve the
situation, but don't rely on it.
The problem here seems not to be just the transition from the old XAA to the
new EXA. The bug is somewhere deeper, and it looks like to be an interplay of
various things in the intel driver itself, the kernel, the X, the usage of 3D
acceleration by the apps on top of X and so on. That is why crashes appear to
be random, why it is almost impossible to trigger the bug intentionally and
why there is no fix for cca 5 months now.

So much for the famous Open Source support. If it were a nVidia bug, it would
be just fixed in the next release of their closed-source driver. Even ATI's
buggy flgrx driver gets fixed when the bug is severe enough. And here we are
having the source completely open for the intel driver, and a bug that so
radically affects all Intel cards is not fixed for half a year now...

Best, :-)

well i've been using my aspire one on F10 since the day of the F10
release with the exa acceleration method, i'm scoring ~780 in glxgears with
glxgears -geometry 300x300+360+150
as the command, i've yet to have a X lockup or crash either and i'm
using compositing in xfwm4 too, and the plymouth solar boot works well
too. obviously not everyone is having such a good time with their intel
gfx hardware, but not everyone is having problems either ;)
