Just checked. This one was fixed in the -1.1 release.

However, there is a Heisenbug hitting some of the people with a Retina
Z3 AND a 68040 cpu (but not all of them). You're a victim of it.


1) boot NetBSD without active Retina 

1a) you can either take it out of the computer

1b) or get
and use the included "shutup" program to mark the Retina as
shut up, then boot with the gobsd instead of the loadbsd program.

2) install as described in the INSTALL document, always using GOBSD
instead of loadbsd, and remember to read the gobsd.readme to find out
which parameters GOBSD wants.

3) install also the kernel sources.

Log in to NetBSD. 

cd /usr/src/sys/arch/amiga/conf

edit the GENERIC file there; uncomment (remove the hash in front of it) the



Save the file.

config GENERIC
cd ../compile/GENERIC
make depend && make

A new kernel should be built, which should work with your 040 and Retina.
