Panic at boot on 4/330 with cgfour and cgsix

[foo bar <tokenalt%gmail.com@localhost>]

Hello all

So as the subject says I'm having problems with these two
framebuffers. It seems to be related to the issue reported a few
months ago here.

https://mail-index.netbsd.org/port-sparc/2024/04/15/msg002644.html

I don't see the crazy interrupts but both framebuffers trigger a data
fault szerr. For the cgsix I made a video of it but unfortunately the
card died not long after so I can't test further.

Luckily my cgfour is still working and I've attached a dmesg from
current below. Any help would be appreciated.
