Ideally I'd like to get this working with 2.6.9-bb4 since that seems to
be the 'stable' 2.6 UML guest kernel.
Else, can you let me know what code (links to all component patches

Your patch is not applying (no such file, HUNKs failing, etc).

you can save some backporting efforts, work on adding more 2.6

Here's the output from a crash using the associated build. Too several

that I am doing nothing other than booting up the UML to trigger the crash

QEMU running on 64bit host is still not available yet, although it can
emulate 64bit kernel. Other than UML, is there any other
alternatives that I can try to use, to trace through the early booting

Sorry for my mistake - I just read the source code for kqemu and they
do compile for x86_64, so the 64bit host version is supported.
