Hello, I tracked down another regression affecting my PC with R9 380 GPU, running the amd-staging-4.11 kernel on Xubuntu 17.04: After resume from powersave, display freezes when the powersave is triggered from the lightdm locked screen or stays completely black if the powersave was triggered from a logged in user. The regression occurs the first time when I build the kernel including commit 323a1cc8f7d3c40a8e77751d62545de43fa52653. Here is the result from the testing series: 8. Step - crashes bfd40a54f781899ee5b9ddffc459a6eafe2bba86 11. Step - crashes dde557132beb2cfb9e98046936cb3565b21d6f9c 12. Step - crashes 323a1cc8f7d3c40a8e77751d62545de43fa52653 10.

Many regards, Martin Babutzka
