Hi Herbert, Folk have reported a boot hangs on Ryzen systems. A firmware bug can hang SEV commands and thus resulting in a boot hang. To protect against firmware bugs this series add a timeout in the SEV command. I would like to get this logic added in stable tree's as well but this patch will not apply cleanly hence I will rework a different patch for stable trees after this patch is accepted.
