If that's the case, please open a new bug report. Boot the latest Kernel from
drm-tip (https://cgit.freedesktop.org/drm-tip) with drm.debug=0xe
log_buf_len=1M, then attach the dmesg output to the bug report. PSR was just
disabled by defaul on drm-tip so any error messages related to PSR should just
go away now.
