Hi What are the steps to reproduce this problem? How reproducible is the bug? Which platform are you using? Please provide the output of "lspci -nn". Is there any way for you to provide us a complete dmesg? Even better if you are able to boot with drm.debug=0xe. When did this start happening? Are you able to bisect this bug? Bisecting is a _really_ good way to help fixing the bug, and since you're running RC Kernels, maybe the bisect interval would be small. Thanks, Paulo
Timeout. Closing. Please reopen if you are able to provide the requested information.
(In reply to Ander Conselvan de Oliveira from comment #2) > Timeout. Closing. Please reopen if you are able to provide the requested > information. Pardon? The requested information is not relevant to the bug.
If you know how to reproduce it and have all the relevant information, then please go ahead and fix it.
Yes, we just revert atomic...
(In reply to Chris Wilson from comment #5) > Yes, we just revert atomic... I'm afraid it's too late for 4.0. Paulo did ask at least two relevant questions: - how to reproduce the bug and how often it happens? - on which platform was this issue seen? (this might be useful even if the bug is in generic code) Given that over two months went by since he asked those questions and 4.0 was released in the meantime, Mikhail, please verify if you still see the issue with that release. Also, please include dmesg with 'drm.debug=0x1e log_buf_len=4M' in your kernel command line.
[mikhail@corei5 ~]$ journalctl --no-pager | grep 'cut here' [mikhail@corei5 ~]$ it means that no more incidents happened in this machine since 2015-04-17.

Closing resolved+worksforme based on the verification by Mikhail.
