I could also start from the console, so it seems to have a random
element.

Why did I need to start so soon? Because of a second panic.

panic: kernel diagnostic assertion "len <= LINUX32_ELF_AUX_ENTRIES" failed: 
file "/archive/foreign/src/sys/compat/linux32/common/linux32_exec_elf32.c",

This happened during a bulk build, I guess building one of the suse
packages. I'll retry.
