This just happened again with the patches dropped, so it is a separate bug -
just another regression.

I now recall that it has been happening on every fifth-odd boot for a few
weeks now. The machine prints

Time: tsc clocksource has been installed

then five instances of "system 00:01: iomem range 0x...", then it hangs.
ie: it never prints "system 00:01: iomem range 0xfe600000-0xfe6fffff has
been reserved" from

It may have some correlation with whether the machine was booted via
poweron versus `reboot -f', dunno.
