ASRock skylake gpe6F bug: /var/log/syslog and var/log/kern.log are flooded with hundreds of gpe6F errors per second until the root partition runs out of space. Its a known issue with ASRock skylake boards. The workaround is o add [code] echo “disable” > /sys/firmware/acpi/interrupts/gpe6F [/code] to rc.local. more info at https://forums.linuxmint.com/viewtopic.php?f=49&t=223180
