dmesg | tail -n 150
I'm experiencing X crashes, graphical corruption and sudden deactivations of a
VGA monitor using nouveau and dual head with my NV43. I'm seeing the following
from dmesg each time:
[drm:edid_is_valid] *ERROR* EDID checksum is invalid, remainder is N
[drm:edid_is_valid] *ERROR* Raw EDID:
for varying N. There can be one or several consecutive occurrences of EDID
errors for each problem. The remainder displayed (N) is not constant in the
latter case. Every printed raw EDID appears correct however.
Though commonly occurring when starting an X session or resuming from suspend,
this also happens at seemingly random intervals with no apparent correlation
with my uptime or how long my X server's been running. Graphical corruption is
only visible after s2ram.
N.B. Using current Fedora 12 packages, no modifications. Problems did not
occur with Fedora 11 snapshots.
