Hi!

Hmm. I moved keyboard between USB ports, and now 4.10-rc6 no longer
boots. v4.6 works ok. Let me try with keyboard unplugged... no, I
could not get it to work. I believe v4.9 and some v4.10-rc's worked,
but I'll have to double check.

Machine is small Intel desktop:

Last message I can see on console is something like:

pci 0000:00:02.0: Video device with shadowed ROM at [mem 0x000c0000-0x000dffff]

...and then blinking cursor. According to dmesg, v4.6 kernel prints
this just after this message:

pci 0000:00:1d.7: EHCI: BIOS handoff failed (BIOS bug?) 01010001

Any ideas? Let me try to update to current Linus' tree. I guess I
could try to boot with CONFIG_USB=n, but that will be pretty useless
configuration.
