After updating kernel from 5.6.4 to 5.6.5 reboot and shutdown do not work any
more. My laptop Lenovo Thinkpad T495 is simply hanging forever with display
turned off, but the keyboard backlit and power led on.
I did bisection and it points to
drm/amdgpu: fix gfx hang during suspend with video playback (v2)
kernel stable 5.6.x commit: a1f57b87ddcc869b576aca73608f35cb436c3fdc
kernel stable 5.4.x commit: bdac1d76a310578b3ad081df2db97da59e241010
Indeed, after reverting this commit, both kernels reboot or shutdown properly.
