If I could blame your crash on any of the recent patches I would but its something new and unfun. Most of the fixes in the Linus tree are directly from fixes to Fedora/Ubuntu bug reports. even after reviewing the dmesg I can't see why its failing on that system, If you could build 2.6.32 on that machine with the staging flag enabled and see if it works it would at least tell us if it is something in recent times or just something thats always been there. Unless some other option in make allyesconfig is conflicting and we've never hit it before. Fedora is close to allyesconfig but not pathalogical like allyesconfig is.
