So it looks difference is probably in "where is keyboard plugged in" but in "reboot" vs. "cold boot". I did not do a cold boot in quite a while :-(. Booting to grub, then hitting ctrl-alt-del is enough to make it work. Ouch. It happens with current Linus' tree. "usbcore.nousb usbcore.nousb=1" on kernel command line does not help. So maybe it is not USB after all. (Sorry). > Last message I can see on console is something like: > > pci 0000:00:02.0: Video device with shadowed ROM at [mem 0x000c0000-0x000dffff] If I do the reboot dance with 4.10-rc6, messages around the hang are: [ 0.281948] RPC: Registered named UNIX socket transport module.
