** Description changed: + [Impact] - [Impact] - - crash can't be used on ubuntu trusty, utopic and vivid + crash in ARM64 can't be used on ubuntu trusty, utopic and vivid when + debugging a new kernel like 4.1-rc+ [Test Case] sudo crash ~/vmlinux + crash will exit with failure log of 'crash: invalid/unknown page size: + 6144', see detailed steps in [1]. [Regression Potential] The proposed patch has been merged upstream, so there shouldn't be - potential regression + potential regression. + + Also These changes are to code that only gets compiled on arm64, so + there's no risk to other architectures. [Other Info] - - After running crash from trusty, the failure log in [1] can be observed. Then I built crash from wily directly, the similar failure[2] can be observed too.
