:I've also noticed that I get messages like these during the startup of
:windows under VMware (possibly a property of the wiring behavior
:previously described):

:Normally I'd think this was an impending IDE drive failure, only a number

This message occurs when the system is trying to swap pages in and
I/O queued to the swap device (aka hard drive) does not complete
after 20 seconds. The swapper will still wait until the I/O
completes.
So something is tying up your IDE bus for 20+ seconds.
