After the PCI bios merge into -stable, my old CTX laptop boots with
the following (full boot -v below)...
...

...no difference with or without the ignore_pcibios patch
(no-hang.diff.4).
Other than the occasional 'ed1: device timeout', the laptop
is happily running 4.3-20010810-STABLE.
This laptop currently serves no useful purpose and can be
used for debugging if need be.
