So does HEAD never panic but 10 often panics?  The odd thing here is that this 
should be a static table generated by the BIOS that should have the same 
contents every boot.  The panic is claiming that one of the fields in the 
table is set to an invalid value.  If it happened on every boot it could be a 
software bug (or a BIOS bug we need to workaround).  If it only happens on 
certain boots it feels more like a memory error. :-/
