@jsalisbury: I had the machine tested with this kernel: Linux xa-xubu 4.18.0-041800rc1-generic #201806162031 SMP Sun Jun 17 00:34:22 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
that I found via your link [0]. The result is that in this kernel, the problem is gone. So that sounds like good news! I think there was another commenter asking me to try a (probably different) upstream kernel, but it seems gone now. To them I can report that I didn't try building a kernel myself, but hopefully their proposal was close enough to using the Ubuntu mainline kernel that this test gives them the answer they are looking for. ** Tags added: kernel-fixed-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1777245 Title: X freezes with kernel 4.15.0-23-generic (AMDGPU) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1777245/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
