On the blades two drivers are triggering this on the blades:
tg3
mptbase

The problem is the address that is coming in is less than 4096 ( strange but
it's happening)...here is part of one of my traces(have to hack linux so that
the I can get the rest...the output is getting corrupted when coming through the
serial console):
<ffffffff80101880>{init_level4_pgt+2176}
       <ffffffff8010db5b>{error_exit+0} <ffffffff80101880>{init_level4_pgt+2176}
       <ffffffff80116e70>{do_page_fault+432} r_attach+70}
<ffffffff80248f8e>{bus_add_driver+142}
       <ffffffff801090d2>{init+178}

Now this is from compiling on Fedora 4 x86-64 using gcc4. More to come.
