>Description:
Using the setup described at https://wiki.netbsd.org/wiki/RootOnZFS/ the kernel panics during load with an ATI FirePro 2270 x1 as the console device and radeon* enabled.

(handwritten transcript)
kern info: [drm] Loading CEDAR Microcode
r600_cp: Failed to load firmware "radeon/CEDAR_pfp.bin"
{drm:netbsd:evergreen_inot+0x374} *ERROR* Failed to load fi...

radeon0: error: Fatal error during GPU init
radeon0: unable to register drm: 2
panic: chosen: no console device

I also built a custom Ramdisk with the firmware on it at /usr/libdata/firmware/radeon, but that did not change anything.

When not booting to the ifs root, the card works, but without acceleration.  
kern info: [drm] ring test on 0 succeeded in 1 usecs

radeon0: autoconfiguration error: error: disabling GPU acceleration

>How-To-Repeat:
follow the instructions at https://wiki.netbsd.org/wiki/RootOnZFS/ with an ATI Radeon installed as console device.  Probably with any card that loads microcode from the filesystem.
While at it, find that the system cannot dump core...

 i see this on a radeon 5450 on a ryzen 5600G system.  fortunately
 the CPU is fast enough that mostly i don't notice/care but i've
 not figured out what is going wrong -- the test is waiting for a
 different value to come from the write, and it never doesn't, but
 i don't know anything about how this ring is supposed to work.

 what is your CPU/mb/etc?

 You mean a new PR for the missing accel?

 This is a HP Z240 with one Xeon E3-1270v6

 should the complete dmesg pasted into the PR?
 And, should there be a separate PR for the 4 detected connectors when =
 there are actually only two (no DP available=E2=80=A6
