Try adding this to /boot/cmdline.txt
slub_debug=FP
So your cmdline.txt would look like:
slub_debug=FP dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait
Then reboot.
Might also be a good idea to add this in /etc/sysctl.conf and do sysctl -p:
kernel.panic = 10
This will automatically reboot in case of a panic. You should make sure your miner automatically starts up.
