Ok, just put in the 64Gig kernel again, it had a different kernel I
couldn't find the source for. The box booted and recognizes all 16Gig
but we see this now:
Unable to handle kernel paging request at virtual address 00102004

Talking to co-workers, this is the reason for changing the kernel.
Supposedly the memory has been physically troubleshot(?) in the past
including swapping out physical dimms. If the memory is limited to
<6Gig this doesn't happen.
Thoughts or should I ask the kernel mailing list?
