I tried to force intel driver instead of modesetting and the messages are gone. So I guess it's some bug in modesetting driver. Created attachment 134308 [details]

kernel config for forced intel tests
This may be related to 102759. I downgraded my kernel to 4.11.12. Everything seems to work good again. No strange messages in dmesg and Ctrl+Alt+F1 works again (With 4.12+ it doesn't work) No errors with 4.14 + modesetting. I guess it's fixed. (In reply to Rion from comment #9) > No errors with 4.14 + modesetting. I guess it's fixed. Thanks for the update Rion. Marking as resolve then. |
