Arguably, OpenBMC should fix their code to respond in a sane timeframe.

Not arguably actually, they should do that full stop. do we have a bug
open on that for them?

Hrm... should we/do we expose this in any way to userspace?

Also wondering if we should log somewhere how long all of these things
took... if it's >5 seconds now, that's... as long as it takes to boot to
petitboot from starting the kernel.
