I've built a v4.1.18 kernel binary with the relevant scsi driver patches.
Some of these patches appeared in v4.5-rc1, others are not yet merged.
Hopefully when v4.5 is released it will contain all of these patches.
This kernel is fairly minimal. It doesn't include any complex filesystems
for example. But it is reasonably small considering that all of the
drivers necessary to boot are built-in (no initrd required).
I tested this build on my Mac LC III and it booted from a scsi disk. It
took a while. Sequential read from disk runs at about 22 KBps when using
PIO on the LC III. The Mac IIfx will do better. But you could also boot
from NFS or ATAoE.
For stability reasons, I've omitted the Egret driver. So if you use this
build on a LC III or similar, you'll need to use a serial port or a NIC to
log in.
