Hi,
Hi again, in Endless we are still actively working with DC on several laptops, so I just wanted to give you a quick update regarding the regressions indicated in Daniel's email.
- System hangs on S3 resume.
Bug can't be reproduced when booting with amdgpu.dc=0 Also reproduced with DC on Linus master (4.15-rc), but appears fixed on agd5f/amd-staging-drm-next https://bugs.freedesktop.org/show_bug.cgi?id=104281
This keeps being an issue. Unfortunately (as stated in the bug report) this problem is still reproducible on the agd5f/amd-staging-drm-next branch (tested it today with HEAD at 95b5f44) even though the frequency is not high (maybe 1/10 suspends or less). In the bug report you can find the dmesg log if interested.
- Display corruption when using multiple displays

I was able to bisect this problem down to 1 specific commit (see [0]).

This was indeed fixed in on Linus master.
Thank you very much for the DC work!
