Any suggestions/ideas on how to track this down?


Connect a null modem serial cable and outb printable characters to 0x3f8 at various points in the assembly code (immediately followed by an infinite loop, or characters may not be emitted on the serial line before the system crashes). As you say it crashes pretty early, so you won't have to move the debug output around very much to work out which instruction is causing the crash.
