Bug Description
ThinkPad 25, UEFI mode, Ubuntu 18.04 installed as a _live_ distro in FAT32 partition on SATA SSD in WWAN slot.
Grub options allow booting without persistence or with a 256MB persistence file. Only thing "persisted" is TERM in favorites.
Without persistence all is well. With persistence snapd uses up to 90% CPU - perhaps more - and cripples the system. Fan runs nearly full speed constantly.
I can eliminate the problem by removing snapd - and that persists. Can't kill snapd. PID is constantly changing.
0% fan and low CPU use at idle w/out snapd with persistence, or booted w/out persistence.
WORKAROUND:
sudo systemctl stop snapd
