Bug Description
Description:
Raven 2 platform fails to boot on ubuntu 19.04 (disco) with kernel 5.0.0. The issue is related to a fixed patch in linux-mainline about psp response code status.
In some cases, psp response status is not 0 even there is no problem while the command is submitted. Some version of PSP FW doesn't write 0 to that field. So here we would like to only print a warning instead of an error during psp initialization to avoid breaking hw_init and it doesn't return -EINVAL.
Steps:
1. Install Ubuntu 19.04 daily build on AMD Raven 2 platform (reproduced with 2019.03.18 version)
2. Reboot and it fails at kernel initialization.
Current patch status:
A patch has already accepted in the linux mainline. (id: 466bcb75b0791ba
See: https:/
Backport status:
A backport patch is available and verified.
