+qemu-system-m68k virt machine doesn't boot Linux kernels using 68020, 68030 and 68060 CPUs
+Description of problem:
+QEMU doesn't seem to be able to start Linux kernels using a CPU other than a 68040 (which does work fine)
+
+To rule out host issues, the issue is reproductible on Debian Unstable amd64 (with version QEMU emulator version 9.2.0)(Debian 1:9.2.0+ds-5))
+
+To rule out cross-compilation issues, the kernel has been rebuild inside a virt machine (using a 68040 CPU), running Debian Unstable 
+
+Each CPU model below gets stuck early before kernel boot during the ABCGHIJK thing. The Kernel doesn't seem to boot and QEMU process eat 100% of a CPU physical core
+
+**68020**
+```
+qemu-system-m68k -M virt -cpu m68060 -m 1G -nographic -kernel /home/demik/tmp/vmlinux
+ABCGH
+```
+
+**68030**
+```
+qemu-system-m68k -M virt -cpu m68060 -m 1G -nographic -kernel /home/demik/tmp/vmlinux
+ABC
+```
+
+**68060**
+```
+qemu-system-m68k -M virt -cpu m68060 -m 1G -nographic -kernel /home/demik/tmp/vmlinux
+ABC
+```
+Steps to reproduce:
+1. build a kernel with 68020/030/060 support (using virt_defconfig as base)
+2. start QEMU with the command line above
+Additional information:
+68020 is understandable as it may need some sort of 68851 emulation.
+
+Relevant Kernel config Processor configuration:
+```
+#
+# Processor Type
+#
+CONFIG_M68KCLASSIC=y
+# CONFIG_COLDFIRE is not set
+CONFIG_M68020=y
+CONFIG_M68030=y
+CONFIG_M68040=y
+CONFIG_M68060=y
+```
+
+This may be related to the following issues (but I don't have the skillset to confirm that)
