Errors "ERROR UVD not responding, trying to reset the VCPU!!!"

Solution 1:

I had a very similar problem and fixed it by editing the default grub file with

  sudo nano /etc/default/grub

and changing the line

  GRUB_CMDLINE_LINUX=""

  GRUB_CMDLINE_LINUX="radeon.modeset=0"

then saving the file and updating the grub with

  sudo update-grub

and rebooting. If the above does not work then perhaps try out changing the

  GRUB_CMDLINE_LINUX="radeon.modeset=0"

  GRUB_CMDLINE_LINUX="nomodeset"

. And check the dmesg log for errors with

 dmesg | grep radeon

if the above methods work just to make sure everything is Ok.
