Starting X just gives a black screen, and the log is filling up with:
(EE) RADEON(0): Idle timed out, resetting engine...
A forum post (from another guy) indicates that removing 2 GB (from 4 GB) of RAM from the laptop fixes a similar issue with -radeonhd, but this has not been confirmed by the reporter on -ati.
Another thing that looks contradicting in the log:
(EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM
[dri] Disabling DRI.
...
(==) RADEON(0): Will attempt to use R6xx/R7xx EXA support if DRI is enabled.
(**) RADEON(0): Using EXA acceleration architecture
He also tried to force XAA in xorg.conf:
(**) RADEON(0): Option "AccelMethod" "XAA"
but it does not take effect. Is it supported?
The driver is built from git 945ccbbd4fa2b65ccdfb23716c178c95b036734d
