Honestly, that old behavior seems to be the *much* better behavior.

A synchronous stall at boot time is truly annoying, and a pain to deal
with (and debug).

That pci_vpd_read() function is clearly NOT designed to deal with
boot-time callers in the first place, so I think that commit is simply
wrong.

And yes, I see that "128ms timeout". If it was _one_ timeout, that
would be one thing,. But it looks like it's repeated over and over.

Not acceptable at boot time. Not at all.

Bjorn. Please revert. Or I can do it.
