Thanks for testing! I think we're still missing a test with https://kernel.ubuntu.com/mainline/v7.1/. I suspect you're hitting ISM related issue, as 7.0.0-28.28 added https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/resolute/commit/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c?h=Ubuntu-7.0.0-28.28&id=707d6e61c3418f9fa79235dbf11b51062aec18d7
Later on there were two fixes related to ISM merged to upstream: https://github.com/torvalds/linux/commit/17edfa32f1496df914b355cf7c0711a481765446 - included in 7.1 mainline kernel https://github.com/torvalds/linux/commit/3714fe242592e3699ac5e2c19d68b275a210be7d - included in 7.2-rc5 mainline kernel Right now we have to check which one of these is actually fixing your problem. We already have a test with 7.2-rc5 which includes both fixes. We need to test mainline 7.1 now, if it works for you then 17edfa32f1496df914b355cf7c0711a481765446 is the answer. If not then probably 3714fe242592e3699ac5e2c19d68b275a210be7d or both fixes are needed. Please test https://kernel.ubuntu.com/mainline/v7.1/ for me, you may need to adapt the workaround script. Exact kernel version should be "7.1.0-070100-generic" for mainline 7.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163121 Title: [Regression] Laptop fails to power off completely when HDMI is connected in kernel 7.0.0-28 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2163121/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
