After upgrading to rc7 from rc6 on a system with NVIDIA GP104 using
the nouveau driver, I get no display output from the kernel (only the
output from GRUB shows on the primary display). Nonetheless, I was
able to SSH to the system and get the kernel log from dmesg. I found
errors from nouveau in it. Grepping it for nouveau gives me this:
[ 0.367379] nouveau 0000:01:00.0: NVIDIA GP104 (134000a1)

[ 0.485078] nouveau 0000:01:00.0: probe with driver nouveau failed with error -50
I bisected between v6.9-rc6 and v6.9-rc7 and that identified commit
52a6947bf576 ("drm/nouveau/firmware: Fix SG_DEBUG error with
nvkm_firmware_ctor()") as the first bad commit. I then rebuilt
v6.9-rc7 with just that commit reverted and the problem does not
occur.
Please let me know if there are any additional details I can provide
that would be helpful, or if I should reproduce the failure with
additional debugging options enabled, etc.
