I have this bug on 12.04.3: [14683.999394] [drm:intel_dp_set_link_train] *ERROR* Timed out waiting for DP idle patterns [14683.999398] [drm:i915_write32] *ERROR* Unknown unclaimed register before writing to 64040
uname -a Linux titania 3.8.0-34-generic #49~precise1-Ubuntu SMP Wed Nov 13 18:05:00 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux So I guess the raring kernel also. I see this message in syslog after I try to log out to switch user, and the screen freezes (goes black and responsive) and ctrl+alt+fn1 is needed. Does this message really have nothing to do with the "crash" then? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1138700 Title: Using eDP leaves kernel log with "Timed out waiting for DP idle patterns" messages To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1138700/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
