(this may be https://bugzilla.kernel.org/show_bug.cgi?id=204241 ?) - The keyboard locks up, but I can still login via SSH - 'sudo shutdown now' will never finish. The kernel is stuck - In my case dmesg nor xorg.log notice at all something went wrong - Trying to kill X reveals the following: [ 1571.941734] Call Trace: [ 1571.941747] __schedule+0x293/0x720 [ 1571.941752] ? __queue_work+0x14c/0x400 [ 1571.941758] schedule+0x33/0xa0 [ 1571.941765] rpm_resume+0x108/0x780 [ 1571.941769] ? __switch_to_asm+0x40/0x70 [ 1571.941776] ? wait_woken+0x80/0x80 [ 1571.941782] __pm_runtime_resume+0x4e/0x80 [ 1571.941939] amdgpu_drm_ioctl+0x39/0x80 [amdgpu] [ 1571.941944] do_vfs_ioctl+0xa9/0x640 [ 1571.941950] ? __schedule+0x29b/0x720 [ 1571.941954] ksys_ioctl+0x75/0x80 [ 1571.941957] __x64_sys_ioctl+0x1a/0x20 [ 1571.941964] do_syscall_64+0x57/0x190 [ 1571.941968] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [ 1571.941973] RIP: 0033:0x7f746d5a96d7 [ 1571.941982] Code: Bad RIP value.
