I'm not sure. Maybe you need a NetBSD-current (5.99) userland.

I could upload the files, if you want. This would be a good basis for
further test-kernels.

Hm. But why are there some A1200-owners without this problem, like John
Klos? What is the difference?

From the source (gayle_pcmcia.c) I would guess that IRQ level 6 is used for
inserting/removing a card and IRQ level 2 for data.

A few days ago I checked the differences between the source of the last
working kernel (4.0 or 4.0.1?) and 5.0. In the Amiga-specific source there
are *no* differences at all!

The kern source is used by A3000s and A4000s as well. So maybe there are
changes in the PCMCIA code causing this behaviour?

For another test I compiled a minimal kernel with just a few devices to make
the system start. There is no PCMCIA code in this kernel. Please have a look
if it makes any difference:
