--- Comment #4 from EvaWang <evawang at linpus.com> ---

> 1. Is this reproducible?
>    1a. If yes, please submit dmesg with drm.debug=0x6
        Eva:Yes, please refer attachment dmesg_315rc8.log
>    1b. If no, please lower the priority
> 2. Is this a regression?
>    2a. If yes, please bisect.
        Eva: It seems 3.15 has the issue, but 3.14 has no issue. we will spend
hours to verify whether it is a regression.  which branch  do you suggest to
bisect?
> 3. What were you doing at the time of the hang?
        Eva: I enter to tty4 to get the dmesg and error. if do not press tty4,
system will hang and can't enter to tty even if press tty4.
> 4. Did the system recover after the hang.
       Eva: It can't recover.

> 5. Please try to reproduce with rc6 disabled.
       Eva: It still happen with rc6 disabled.
