--- Comment #40 from Andreas Reis <andreas.reis at gmail.com> ---
So after finally getting round to bisect, the commit after which the freezes
occur is:

dri3: For 1.2, use root window instead of pixmap drawable
https://cgit.freedesktop.org/mesa/mesa/commit/?id=03a61b977e1f6adb64658aa059ce53e766ff9ad9

Tested by reverting it from latest mesa master & compiling with the old patch
(also using git versions of xserver and xf86-video-intel). No new freezes so
far.

(The freezes had continued with having "sna: Disable the reduced flush
optimisation" applied. Dunno if it actually does anything, but I've reverted
that revert as it doesn't hurt.)
