<br>
Many regards,<br>

Betreff: Regression: Crash/freeze when resuming from suspend or locked screen<o:p></o:p></p>
<p>Hello there,<o:p></o:p></p>
<p>Sorry it is me again with another regression. I just built the latest<br>
amd-staging-drm-next and the issue which was already reported here:<br>
<a href="https://github.com/M-Bab/linux-kernel-amdgpu-binaries/issues/29">https://github.com/M-Bab/linux-kernel-amdgpu-binaries/issues/29</a><br>
and which I can confirm is still existing.<o:p></o:p></p>
<p>The issue is caused occasionally when re-enabling the display from<br>
either suspend or from a locked screen. The frozen image can be black,<br>
a weird colorful pattern or the login screen. Attached you can find the<br>
kernel crash+trace error I just caught.<o:p></o:p></p>
<p>So far I have no idea when it was exactly introduced. I asked the other<br>
users if they are able to give me a time range I will try to bisect it.<o:p></o:p></p>
<p>My setup: Xubuntu 17.04, patched amd-staging-drm-next kernel, R9 380<o:p></o:p></p>
<p>Many regards,<br>
Martin<o:p></o:p></p>
