Not to sound defensive, but I'm fairly sure this isn't an
fdisk-related problem. The partitions that fdisk creates follow the
spec as far as I can see.

These partitions look quite sane. I wonder, though, if there's
something about your specific partitioning that is confusing the
kernel's SGI disklabel support.

I rather suspect that this is the same problem that causes the request
for the out-of-bounds block in the first place: kernel memory
corruption. Unfortunately I have few ideas as to what the specific
problem is. I would start bug-hunting in the sgi disklabel kernel
parts. Make sure that it's compatible with what fdisk is doing.
