I performed some reverse commit bisect and thus tested some 4.X kernels. Here's the result:
1) The bug is present in all 4.4.X kernels until kernel "4.5.7-yakkety" (build 4.5.7-040507-generic), which's the last one carrying the bad commit. Starting on kernel "4.6-rc1" (build 4.6.0-040600rc1-generic), the bug is gone. Hence, a "good commit" removed the bad commit on 4.6-rc1. ** Attachment added: "Comparision chart among buggy and non-buggy 4.X kernel versions/builds." https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/1608042/+attachment/4714518/+files/COMMITS.pdf -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1608042 Title: 64-bit XUbuntu 16.04 "Xenial" hybrid graphics (Intel + AMD): AMDGPU crashes / freezes / hangs entire system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/1608042/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
