We're encoding the file-and-line information in the program text immediately after the undefined opcode, so you'll always see junk in there. Sorry.

I think Keith said that ksymoops supports that. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
