    Subject[bisected] offset display bug in i915
    From
    Date
    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

    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.
