ext2 is compiled for 020-60:m68k-atari-mint-gcc -I../.. -D__KERNEL_XFS__ -m68020-60 -Werror -mshort -g -O2 -fomit-frame-pointer -Wall -Wmissing-prototypes -Winline -Wshadow -Wpointer-arith-Wcast-qual -Waggregate-return -c bitmap.c -o bitmap.o and libkern040 is used! So it's no surprise it does not work on 68000. Someone should fix this (asap).
Hopefully by compiling the modules for the same CPU as the kernel. Compiling the modules for 68000 does not make much sense since "everybody" are using Falcons or better.
