Unfortunately we need the very first crash message that happens, but
even your first snapshot is after other crashes have occurred.

You'll need to build a kernel with CONFIG_BOOT_PRINTK_DELAYED enabled
and then you can boot with boot_delay=xxx (where "xxx" is something
like 100, it's in milliseconds) to slow down the message printing so
that you can capture the first message cleanly.
