Have you been able to work around this problem? For me, when this happens on boot, it hangs the boot process. (ctrl-alt-delete still works)
If I specify enable_guc=0 or enable_guc=1 it will boot, but these messages still litter dmesg. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2002011 Title: drm_WARN_ON in __intel_tc_port_lock Status in linux package in Ubuntu: Confirmed Bug description: These warnings are presented in my kernel logs when I boot.
