As I mentioned on the -user list, when I build 2.6.15-rc1 or -rc2 on my x86 laptop, it works just fine as long as PID 1 never forks. As soon as fork() gets called, I get the attached panic.
I'm not sure how to go about debugging this. Is it the clone stub handler again, do you think? This is an area where I don't particularly understand how it worked in the first place. I can go stare at 2.6.14 (which works) and try to work out what changed...
