What is DWARF2 - a better version than DWARF :( I don't know what the crash is about, but I think (never positive about this stuff :-) that the dwarf2 message has nothing to do with the crash. The crash is due to something else, the kernel is trying to print a backtrace and it can't do the backtrace because the debug info it relies on is busted (or the code reading the debug info is busted). Part of the dwarf2 debug info standard (or gnu extensions to it) includes special section in the object file which, in theory, describe stack frames well enough to backtrace through them (but anytime you hit hand coded assembly, you usually hit hand coded frame descriptions too and they are always wrong :-).
