Thanks Brandon, I don't see anything in the log that looks suscpicious.

Should a kernel fail during boot, I'd suspect it doesn't like one of the apm/pcibios callbacks, or it doesn't like one of the smbios/mptable/acpi tables. You could try compiling the SeaBIOS code (see http://seabios.org/Download ) and increasing the debugging by modifying src/config.h. Specifically, you could increase CONFIG_DEBUG_LEVEL, and set DEBUG_HDL_pcibios32 and DEBUG_HDL_apm to 1. Also, you could try disabling some of the features to see if that prevents the fault (eg, disabling CONFIG_ACPI / CONFIG_SMBIOS / CONFIG_MPTABLE). -Kevin
