Under loader prompt type "unload", and than "load kernel" with required
modules one by one and type "boot" at end.

This will not work if malo is part of kernel itself.

backtrace from textdump can help debugging crash, but use "kldload
if_malo" after
boot so that dumping can actually work, in other words use loader.conf only when
you know that driver is actually stable/working.
