I have two coreboot trees. As far as I can tell they're identical. One produces working ROM images, and the other reboots when it jumps to the payload.
That was the key. I hadn't done a make clean in the working tree. Rev 4000 broke it for me, but I'm still not sure why. Once I was doing make clean every time I could find the revision that was breaking. It looks like Rev 4000 changed the compile flags, so that's where I'm going next. Everything else in 4000 looks innocuous to me.
The question is why these compiler flags for coreboot make SeaBIOS panic. I'm still trying to narrow it down, but if you spot it first that would be great!
Thanks, Myles
