It is if you have your BIOS configured incorrectly with
regard to whether you are running a "PNP OS".
It's also normal if you have more hardware in a box
than it's possible to handle simultaneously, e.g. if
you had a bunch of slots full of resource hungry
hardware.
Probably you will need to fiddle with your BIOS.
Try the following patch; the failure message will be
somewhat less cryptic, since it will tell you the
proximal reason for failure out of the 5 possibles
for the message you are seeing. 8-).
