There are several memmoves in that vicinity; could you show us the line and some surrounding context?
"kernel stack not valid halt" is coming from SRM, right? I'm surprised that your alpha didn't come with a 2114x, and that SRM's bootp/tftp loader can drive any other kind of ethernet card. Does your 82559 have PXE enabled or have the additional chip added with bootp and tftp boot burned into it (there's a socket for it on most ethernet cards)?
