I also saw this problem in the past (a couple of months ago), mostly on a specific machine. But I _am_ playing with the linker scripts so I expected to be the cause in an unknown way.
Unfortunately I've never understood the cause (I also switched from reiserfs to ext4 in the panic, moving the source tree around seemed to help). The behaviour seemed inconsistent and could not reliably reproduce it even if there were very few "moving targets". Very clueless.
Don't know why I'm not encountering it any more but a more useful diagnostic would be surely useful. The second pass thing didn't help me either. I also tried to implement an addition pass but the thing was not making any sense to me anyway.
So yes, in case of error please leave some trace somewhere so that to poor user has some chance to work his/her good luck out of the troubles.
cheers, Domenico
