EDID checksum errors
The following EDID checksum errors are spamming my syslog.

Yes, that is the patch I've linked to above. But it just papers over the problem.

Don't take it personally; lots of monitors suck. That patch just gives you the option to forcibly use monitors with EDIDs that have bad checksums, in case the checksum is the only bad part of an otherwise valid EDID. -- When the facts change, I change my mind.
