Created attachment 137911 [details] Initialization output on SMU firmware load.

Created attachment 138467 [details] backtrace trying drm-4.17 As stated in bug 105760, drm-4.17 didn't make any difference for me, though, setting acpi_backlight=intel_backlight, as mentioned in(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1656649), allowed me to boot once without any backtraces, using an stable kernel: $ DRI_PRIME=1 glxinfo ...

I'll try to reboot several times to see if the work around works always, and let you know about it. Thanks! José.
So far no luck, seems like with the acpi_backlight and removing laptop mode from my services initialisation gives more chances to successfully boot without issues, but eventually the bug will turn up.

aw, and yes, if I don't blacklist the module, the trace happens, which certainly blows my mind, as it's built in, modprobe shouldn't affect it. José.
