I found that the Broadcom wireless chip is waking the machine up from STI / freeze. A workaround is INTERFACE=wlp58s0 ifconfig $INTERFACE down modprobe -r brcmfmac && echo freeze > /sys/power/state && modprobe brcmfmac ifconfig $INTERFACE up I thought I would ask whether I should report this as a bug, and if yes, where.
