Xorg -intel crash in uxa_copy_n_to_n on suspend/resume on Dell D830 (UXA bug)

Binary package hint: xserver-xorg-video-intel

When I suspend and resume my laptop in jaunty, the X server always crashes and restarts. I attached a gdb to it and got this backtrace:

Program received signal SIGABRT, Aborted.

I am running with AccelMethod uxa and I have also SKIP_CHECKS=yes in .config/compiz/compiz-manager to enable compiz. I will try without them, but I'm pretty sure that at least compiz has nothing to do with the problem.

Wich UXA disabled, suspend/restore works fine. So this seems to be an UXA bug.
