That's a lot of work on a 030 Mac - have you tried to reproduce this on
any kind of emulator?
I suppose one difference between your 030 and 040 Macs might be the
amount of RAM available. I wonder if this bug results from a combination
of 030 MMU and memory pressure, or 030 MMU only.
As to emulation... 030 and 040 MMUs differ a lot.
E.g. Aranym emulates only the (simpler) 040 MMU, and does not emulate
CPU cache. Qemu does not have any cache emulation either.
WinAUE (and Hatari & Previous) emulate both 030 MMU and CPU cache.
Using Hatari with Linux is documented here:
https://hatari.tuxfamily.org/doc/m68k-linux.txt
AFAIK 030 MMU + cache emulation works well enough in WinUAE (Amiga
emulator) to run Linux kernel + user-space, but with Hatari (Atari
emulator), you need to disable cache emulation to have working
user-space with m68k linux.
