I built an x86_64 image and turned on crash logging, and then forced a crash with:
echo c >/proc/sysrq-trigger it rebooted, but when it did there was nothing in /sys/kernel/debug/ (i.e. no crashlog file). What am I missing? Does this not work with x86_64? -Philip > On Feb 23, 2017, at 10:27 AM, Philip Prindeville > <philipp_s...@redfish-solutions.com> wrote: > > Thanks for that. > > >> On Feb 22, 2017, at 11:44 PM, Syrone Wong <wong.syr...@gmail.com> wrote: >> >> According to LEDE's source code: >> >> config KERNEL_CRASHLOG >> bool "Crash logging" >> depends on !(arm || powerpc || sparc || TARGET_uml || i386 || x86_64) >> default y >> >> https://github.com/lede-project/source/blob/master/config/Config-kernel.in >> >> It is enabled by default on some targets and will be available at >> `/sys/kernel/debug/crashlog` on next boot after crash. >> >> The implementation detail can be found here: >> https://github.com/lede-project/source/blob/master/target/linux/generic/patches-4.9/930-crashlog.patch >> >> >> Best Regards, >> Syrone Wong >> >> >> On Thu, Feb 23, 2017 at 10:05 AM, Philip Prindeville >> <philipp_s...@redfish-solutions.com> wrote: >>> Hi, >>> >>> Has anyone managed to use kdump with OpenWRT/LEDE? >>> >>> I have a box which periodically panics, and since /var is a link to /tmp/ >>> there are no persistent logs.
