The bisection will be pretty small and probably point to the last patch.
I assume that lkp-04 is the machine name. What sort of machine is it?
Does it have an unusual Kconfig that I might be missing a case for?
What userspace is it running? Maybe there is a chance I can duplicate
it. I assume fake/boot/1 is a test case that just boots the machine but
does it do anything else?

Thanks.
