Hi Chris,
The following patch that you recently committed breaks my ASUS Eee PC 1015PEM by causing the display to be offset by about 1 inch (a few centimeters) when the mode is (re)set during boot. I previously posted both photographs and video of the problem in another "PROBLEM" thread.
Here is the offending commit found through bisection:
219adae138513bae20b256f1946b9cb3b75ca05c is the first bad commit commit 219adae138513bae20b256f1946b9cb3b75ca05c Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Sep 16 23:05:10 2010 +0100
drm/i915: Cache LVDS EDID
We assume that the panel is permenantly connected and that the EDID data is consistent from boot, so simply cache the whole EDID for the panel.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
I'll look at the patch. Either the EDID is *not* consistent (in which case, why are we not seeing other bugs like this?) or there is something specific to this system or panel used.
Jon.
