I often get these when booting with a SATA disk while using the "ide"
bus manager. Switching to the newer "ata" bus manager replacement
often gets rid of the page faults, but it has some drawbacks:

1. It currently only supports PIO mode - no DMA support, thus it's a bit slower.

2. It may not yet support ATAPI (I know this used to be true, but
perhaps this is no longer true - one would have to ask Marcus) - which
means CDROM drives may not work any longer with it.

To switch to the "ata" bus manager, just edit the
src/add-ons/kernel/bus_managers/Jamfile to change where it says "ide"
to "ata" (see here:
http://dev.haiku-os.org/browser/haiku/trunk/src/add-ons/kernel/bus_managers/Jamfile
)

Since the target compiled to the image is the same name, just a simple
re-jam of the image after this should use the new one instead.

I apologize if this isn't the actual cause - but since you didnt'
provide a stack trace, I'm just throwing this out there to try.

On another note, while I know this is somewhat a known problem - is
there a specific Trac ticket for this problem still?
