Framebuffer blackscreen when both monitors are on

when i boot my machine, if i turn on ONLY the “primary” DVI monitor, all is fine.
but if i turn on the secondary one (HDMI) too, the framebuffer goes black.
if i start X all work… but when going back all is still black. dmesg doesn’t say anything.

NVIDIA Corporation GP106 [GeForce GTX 1060 6GB]
kernel 5.17.0-zen1-1-zen
nvidia-dkms 510.54-1
GRUB_CMDLINE_LINUX_DEFAULT=“audit=0 loglevel=3 nvidia-drm.modeset=1 mitigations=off”

all worked before the 510 with the same config…

Thanks in advance.

bug in the 5.17.0 kernel
5.17.1 solved it.
