Sorry, I failed to notice in bug 1940781 that kernel 5.11 is affected. The next step would be to try the latest "drm-tip" kernel from the kernel graphics developers. To do that please:
1. Disable Secure Boot in your BIOS. 2. Download: https://kernel.ubuntu.com/~kernel-ppa/mainline/drm- tip/current/amd64/linux-image- unsigned-5.14.0-051400rc7drmtip20210824-generic_5.14.0-051400rc7drmtip20210824.202108240213_amd64.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/drm- tip/current/amd64/linux- modules-5.14.0-051400rc7drmtip20210824-generic_5.14.0-051400rc7drmtip20210824.202108240213_amd64.deb 3. Install them together: sudo dpkg -i linux*.deb 4. Reboot. 5. Verify the new kernel is active: uname -a ** Tags added: hirsute -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939417 Title: Ubuntu GUI crashes (w and w/o Wayland), VM_L2_PROTECTION_FAULT, amdgpu 0000:09:00.0: [gfxhub0] retry page fault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939417/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
