This failure is by design -- we only allow one hotplug driver to
claim a slot now, and it's "first one loaded wins".

Unless you're talking about something else?

You said that it worked a few days ago, but is hanging now.

Can you bisect it?

Kenji-san, any ideas?

I'm sorry, but I don't have any idea so far.

Yinghai, does this happen even when pciehp is not configured?

Thanks,
