Not sure if it's related to this problem or not but sstate is still not working as intented for me when switching machines, it keeps rebuilding the toolchain when switching machine. What I did this morning:

1) wipe out tmp, sstate-cache, pseudodone
2) MACHINE=beagleboard bitbake u-boot
3) cp conf/machine/beagleboard.conf conf/machine/brokensstate.conf
4) MACHINE=brokensstate bitbake u-boot

And behold:

What I suspect is happing is that angstrom is somehow putting $MACHINE in a var that upsets the sstate logic and/or rm_work upsets sstate and/or something else is broken. The problem is that I have no idea how to debug this except to ping Richard and get the magic diffsigs incantation.
