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.

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=3Dn, but that will be pretty useless configuration.
