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:

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.

Lyude, that's a commit of yours.

Given that 6.9 is due a quick question: I assume there is no easy fix for this in sight? Or is a quick revert something that might be appropriate to prevent this from entering 6.9?

Ciao, Thorsten

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.

Cheers,
