Description Rafael Kitover 2021-03-12 06:11:06 UTC
Photo of error and backtrace on my laptop:


This is 14 current from git built 1-2 days ago.

Laptop specifications:

Model: Eluktronics MECH-15 G2 (gaming laptop, fangtong rebrand)

Processor: Intel Core i7-8750H
Storage: 2x 2TB NVMe SSD
Graphics Card: 8GB GDDR6 NVIDIA® GeForce RTX 2070 Max-Q

Freebsd is installed on the second ssd on a whole disk zfs pool booted via CSM (until I can figure out how to boot it from grub.)

Will be more than happy to provide any other details or do any testing/diagnostics.

I tested this patch:


linked in the linked bug, and it fixes my kernel panic on boot.

Now I have other problems though, for some reason i915kms is locking up on me, maybe because I am booting with CSM, I'll try some things.

Offtopic, but updating kernel to latest git fixed my i915kms lockup.
