output of `journalctl -k` after freeze with option drm.debug=0xe
During or directly after the boot and before the tty login, the system freezes.
It can only be shut down using Magic SysRQ. The system log contains these
errors (full log attached):
[drm:intel_dp_start_link_train [i915]] *ERROR* failed to train DP, aborting
[drm:intel_psr_work [i915]] *ERROR* Timed out waiting for PSR Idle for
re-enable
The second error repeats multiple times per seconds, until the system is
shutdown.
The problem can be reproduced using Linux v4.7-rc3, drm-intel-nightly (8bf2b76)
and the current git/torvalds version (g9cbbef4).
Hardware: Toshiba Portege Z30-A notebook, no additonal devices connected
Linux version: Arch
