Hi, the system fails to initialize your vbios using secureboot (i had a rare chance to on my system to witness it again), for now i traced it to acr_boot_falcon() in "linux/drivers/gpu/drm/nouveau/nvkm/falcon/msgqueue_0148cdec.c" where it throws -110 which is -ETIMEDOUT. You could try to increase the timeout and see if it helps something, similar to the following: diff --git
