Am a bit stuck.
OK, is there anything we could run this with that'd dump more info? (eg debug patches or something). There's bugger all of use that I can see in that stack (and why does __sched_text_start come up anyway, is that an x86_64-ism ?). I suppose if we're really desperate, we can play chop search, but that's very boring to try to do remotely ...
It's a couple-of-year-old 4x newisys box.
