If someone does request_firmware from resume function... that's

Probably pcmcia "ds" driver and CONFIG_PCMCIA_LOAD_CIS.

Well. we'd like to present hardware in working state as soon as we
resume (if eth0 was there before resume, it should be there after
resume. not 3 seconds after resume); so if someone needs to load the
firmware, they should just store it in the kernel memory, and load it
during boot or during (very early) suspend.

Equally arguably, we should just have a "resume_late()" call that can be
used to do this after everything is up and running.

And quite frankly, I don't actually see any reason why firmware loading
shouldn't work in the resume path. I really do think that this is ANOTHER
bug that has no other reason than the fact that that f*cking freezer
killed the system for no really good reason.
