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
