I'm not positive about any of this, but I think the real error is something else. The kernel had a problem and tried to do a stack backtrace (unwinding) from where the problem happened, and that caused the dwarf2 unwinder error. Dwarf2 is a standard for debugging info. The gnu C compiler can generate dwarf2 info, and part of the dwarf2 standard (along with some gnu extensions) describes stack frames and can (in theory) be used to do backtraces through the call stack. Unfortunately the frame description info is hard to get right, and (especially in any hand coded assembly) is often wrong, leading to errors when trying to unwind the stack frames and print info about where the error happened.
