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

I have narrowed it down to SMBIOS. If I disable CONFIG_SMBIOS the image boots up fine.
Gleb, have you seen this thread?
Some of the recent changes to smbios that look like possible culprits are:
Make SMBIOS table pass MS SVVP test Use MaxCountCPUs during building of per cpu tables. Add malloc_high/fseg() and rework bios table creation to use them.
There were other changes, but the comments indicate they were only ports of changes already in bochs. I suppose it's also possible the lack of smbios is turning off some other feature in the guest (eg, acpi) that's the real culprit.
