x86_64 kdb does have the code to follow them, it's pretty much the same. (kdb does have a bug in its x86_64 setjmp with framepointers, but that's irrelevant to whether the x86_64 kernel supports framepointers.) > But kdb should be using a dwarf2 unwinder instead. kgdb certainly > supports that, as does NLKD. In an ideal and bloat-neutral world. I've always imagined it to be quite a lot of work, bringing in its own set of problems: but great that that work has now been done, and yes, it might one day get ported to kdb. But removing "&& !X86_64" is much easier.
