Thanks for your report, might you be able to bisect please the changes
beween 6.12.30 and 6.12.32 then to determine the breaking commit? 

I only see one change beween v6.12.30..v6.12.34 touching
drivers/gpu/drm/nouveau, which is e1fffcd1d75d ("drm/nouveau: fix the
broken marco GSP_MSG_MAX_SIZE"), but I do not immediately why it would
be the cause.

Regards,
Salvatore
