There is only one place that generates this error message, I wouldn't
worry about the function name.

I think it is worth checking the BIOS settings.

The panic is from the code that is setting up the shared memory
stuff.

Looking back, that was where you started. I'm typing this on a machine
running X11 on -current with a radeon card of the same generation as
your one, there haven't been any changes to the old drm driver for a
fairly long time.

Can you try booting the machine without the RAID controller ?

I think there were some locking changes made by riastradh@ to the new
radeon drm driver after Sep 17, is there a newer kernel you can try ?
