on Linux, you might have to echo 1 > /proc/sys/kernel/sysrq before you are
able to echo c > /proc/sysrq-trigger.

this is the current cronjob:
{{{
sysctl -w kernel.panic_on_oops=1
sysctl -w kernel.panic=5
echo 1 > /proc/sys/kernel/sysrq
*/5 * * * * echo c >/proc/sysrq-trigger
}}}
log is in attachment "openwrt r42625 cronjob with kernel crash.log"
after 3 reboots router hang
