Issue with blackbird booting with GPU

r34per:
Ive been trying to figure out an issue that has popped up on my blackbird I just got. I have an AMD radeon rx460 installed, and I copied the firmware to petitboot per the wiki instructions. I have not had issue except for one in particular.

I dual boot void linux and fedora 36 on 2 separate partitions on the same ssd. If I am booted into fedora and I try rebooting, once I get back to the boot menu and I select fedora(void is my default), after a little bit the system will reset on its own(I have no image but I can hear the system make the usual beep it does once petitboot is booted), but when it comes back up I have no picture at all. I plugged a serial cable in and here is the output that I get right before the blackbird reboots on its own-

--- End code ---

After the system reboots on its own, it will boot into the os, I was able to SSH into my fedora os, and I coudl watch the boot process through a serial cable. If I shut the system down either through the os via serial console or just holding the power button, and then powering it back on I can get an image off my video card and boot into the OS just fine. But rebooting is where the issues start. Strangely if I have a serial cable plugged in to the system prior to powering it on the issue doesn't happen at all. I can reboot all day long.

This is not an issue with my void linux partition. I can reboot void linux and select void linux from the boot menu and it boots normally.

If I remove the jumper to enable the onboard hdmi the same thing happens. I also notice the image on the onboard hdmi was really colorful, but it went back the correct colors right as I went to grab my phone to take a picture. The weird colors haven't returned since, so maybe it was just my cable.

With the my rx460 removed and just running off the onboard hdmi I don't get the problem. I then tried another video card I have, an amd r5 240, and it also does not produce the issue. Erasing BOOTKERNFW seems to resolve the problem, so could it just be the gpu firmware? I used the firmware from void linux which has a 5.18 kernel version

ClassicHasClass:
Do you have fast reboot still on?

Something like nvram -p ibm,skiboot --update-config fast-reset=0 as root should disable it.

r34per:
ahh that seems to have fixed it, thanks!

ClassicHasClass:
They really should just ship that way. Fast reboot isn't much faster than regular rebooting, even when it works (which is about half the time).

MPC7500:
Fast reboot isn't much faster? It saves me 90 seconds if active.
