This sounds like a random data overwrite which depends on the exact
kernel layout.  Somebody else in SGI (Prarit ?) said that they compiled
your failing tree on the same platform and their kernel worked.  Since
the build userid and the pathname to the kernel source tree are
embedded in the binary, changing either of those will disturb the
kernel layout, possibly making the problem move.

Jes, try renaming your source tree to something with a different
pathname length and rebuild the kernel.  Does the problem change or go
away?
