List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 31 Jan 2016 01:27:51 -0000 Hi all, It's possible to reliably crash an RPI2 running 11-CURRENT using stress2. In most cases the crash occurs during the syscall tests and then usually the opening line is of the form "translation fault L2" [sometimes L1]. What information is useful to collect for purposes of debugging by others off-host? So far I'm aware of backtrace, kernel and modules, vmcore, core.txt and recently kernel.debug (three places). One update/build/test/crash cycle per day is possible. Thanks for reading, and any guidance. bob prohaska
