https://bugs.freedesktop.org/show_bug.cgi?id=94990 --- Comment #29 from Andrei Dziahel --- Hi, Ok, so it seems I'm affected too: my desktop with GTX970 doesn't boot kernel 4.6 (comes with recent openSUSE Tumbleweed snapshot release). Although it does boot 4.5.4 kernel, from which I'm writing this comment. I've found this issue by googling "timeout at drivers/gpu/drm/nouveau/nvkm/subdev/secboot/base.c:145" message from my logs. Relevant log parts are pretty much identical for me, I can post them here, if needed. Firmware checksums are identical. Haven't tried NvForcePost=1 and pci_msi=off yet, will try later if needed. Anyway, +1 here. Motherboard: Gigabyte GA-MA770 Videocard: GTX 970 by MSI UEFI and SecureBoot are enabled. -- You are receiving this mail because: You are the assignee for the bug.
