Hmm. It hangs during PCI fixups, and it hangs in v4.10-rc8, too.
With debug patch below, I get
...1d.7: PCI fixup... pass 2
...1d.7: PCI fixup... pass 3
...1d.7: PCI fixup... pass 3 done
...followed by hang. So yes, it looks USB related.
(Sometimes it hangs with some kind backtrace involving secondary CPU
startup, unfortunately useful info is off screen at that point).
Any ideas?
Pavel
