I'm having this problem as well. It seems to almost be confined to the i915 chipset. I began noticing the error when I first installed ubuntu a few weeks ago. It didn't affect the performance at all, just a warning I saw on shutdown. This was on 3.0.12-generic (I can give you more specifics if I can get to my server which is at home and internet is down.). Same thing for 3.0.13-generic. Works, but there's that same error message.
When I updated to the latest ubuntu kernel (3.0.15-generic) I get the exact same errors and my system seems to keep restarting X. I have no available shells on Alt-F1, etc, just repeated error message that seems to peg the CPU. When the system did finally get stable (after 5 minutes or so) it was so sluggish as to be unusable. The CPU was probably pegged, but with no shell access I can't say for certain. HTH. I'll provide more if needed. I'll try the echo command and see if it helps tonight. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/712075 Title: [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/712075/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
