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. Linus
