Such a report can provide valuable first-hand information for a Linux kernel maintainer to conduct postmortem debugging. Recently, a repository has been created that systematically collects kernel oopses from Linux users. However, debugging based on only the information in a kernel oops is difficult. We consider the initial problem of finding the offending line, i.e., the line of source code that incurs the crash. For this, we propose a novel algorithm based on approximate sequence matching, as used in bioinformatics, to automatically pinpoint the offending line based on information about nearby machine-code instructions, as found in a kernel oops. Our algorithm achieves 92% accuracy compared to 26% for the traditional approach of using only the oops instruction pointer. %B Proceedings of the 11th Working Conference on Mining Software Repositories %S MSR 2014 %I ACM %C New York, NY, USA %P 52–61 %@ 978-1-4503-2863-0 %U http://doi.acm.org/10.1145/2597073.2597094 %R 10.1145/2597073.2597094 %> https://flosshub.org/sites/flosshub.org/files/guo.pdf
