I think we, both the NetBSD community and the Amiga community, have a few=
=20
things to solve with the BFG accelerators.

Chris Edwards recently made a Youtube video about trying to figure out why=
=20
a BFG9060 has issues in an Amiga 3000:

The video has half an hour long, so I'll summarize by saying that he=20
discovered that the board is perfectly stable without MMULib.

There are a few things worth trying for starters:

If you're running faster than 50 MHz, perhaps try at 50 MHz. This would=20
rule out the possibility that your '060 can overclock fine, but the MMU=20
has issues. This doesn't seem like the problem, but it's worth a try.

Do you have motherboard memory? If so, it may be worth trying to boot just=
=20
using that. If the issue is with DMA to accelerator memory, then using=20
just motherboard memory may work.

Some additional information would help, such as what other cards you=20
have installed, whether you're using motherboard IDE and/or whether you=20
have drives connected to expansion cards, et cetera.

Welcome!

John
