Please try this with

	boot -c
	disable pcibios

That help?

Also try this:

	boot -c
	disable neo

Please send this message back at us, with both of those alternate dmesg
outputs.  This appears to be the early pcibios interrupt mapping problem.

It is affecting a few more machines than we expect.  man pcibios for
more information.
