After upgrading from Ubuntu 20.10 computer stops responding on resume from suspend. The following is printed on the screen during resume attempt:

Bluetooth: hci0: Reading supported features failed (-16)
nvidia-modeset: ERROR: GPU:0: Display engine push buffer channel allocation failed: 0x65 (Call timed out [NV_ERR_TIMEOUT])
nvidia-modeset: ERROR: GPU:0:Failed to allocate display engine core DNA push buffer
nvidia-modeset: ERROR: GPU:0: Display engine push buffer channel allocation failed: 0x65 (Call timed out [NV_ERR_TIMEOUT])
nvidia-modeset: ERROR: GPU:0:Failed to allocate display engine core DNA push buffer

The only option I found so far to recover from it is to forcibly restart the computer.

I am using nvidia-driver-470 (proprietary, tested)

  • I already tried changing the driver version. It didn't fix the issue. – Sergey Jul 30 '21 at 08:15
  • There's a [new kernel bug](https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1925843) that might be at fault. Try booting with an older kernel to see if you still have the problem. – Paddy Landau Aug 14 '21 at 05:47
