This was in linux-next; most recently with next-20220517.
I don't know if that was up-to-date with your patches.
The problem seems to be memory allocation failures.
A sample log is at
https://kerneltests.org/builders/qemu-m68k-next/builds/1065/steps/qemubuildcommand/logs/stdio
The log history at
https://kerneltests.org/builders/qemu-m68k-next?numbuilds=30
will give you a variety of logs.

The configuration is derived from m5208evb_defconfig, with initrd
and command line embedded in the image. You can see the detailed
configuration updates at
https://github.com/groeck/linux-build-test/blob/master/rootfs/m68k/run-qemu-m68k.sh

Qemu command line is

qemu-system-m68k -M mcf5208evb -kernel vmlinux \
     -cpu m5208 -no-reboot -nographic -monitor none
     -append "rdinit=/sbin/init console=ttyS0,115200"

with initrd from
https://github.com/groeck/linux-build-test/blob/master/rootfs/m68k/rootfs-5208.cpio.gz

I use qemu v6.2, but any recent qemu version should work.

Hope this helps,
Guenter
