<!DOCTYPE html> <html><head> <meta charset="UTF-8"> </head><body>Dear AMD graphics developers,I am one of the guys that regularly builds your amd-staging kernels and makes them available for the lazier people. By this we get a nice preview of DAL/DC and you get some free beta-testers.One of the users describe a regression here: <a href="https://github.com/M-Bab/linux-kernel-amdgpu-binaries/issues/8">https://github.com/M-Bab/linux-kernel-amdgpu-binaries/issues/8</a> Unfortunately the bug details are limited but I can give some additional information to pin the bug down: All kernels <= 4.11.3+ (merged with amd-staging-4.11 at Fri May 26 18:19:03 2017 +0200) are reported to be working and the regression was introduced with the kernels >= 4.11.4+ (merged with amd-staging-4.11 at Thu Jun 8 19:44:44 2017 +0200). I attached a list of your commits that were merged in this time range. The other attachment is an X.org log with the trace when amdgpu should be loaded to run a R7 370 GPU. The kernel based on amd-staging-4.9 is not affected.I hope this helps you to find the regression. Just tell me if I can provide further details or testing.Kind regards, Martin Babutzka</body></html>
