[Bug 1767896] Re: Live images with broken seed causes snapd high CPU usage and periodic short GUI freezes

[William D Waddington]

The above "confirmed fixed" link is broken.

If you'll pardon another ignorant question: when does this fix show up
in distro?

Just tried 18.10 and persistence renders live Ubuntu completely
unusable.

Title:
  Live images with broken seed causes snapd high CPU usage and periodic
  short GUI freezes

Status in OEM Priority Project:
  Fix Released
Status in snapd package in Ubuntu:
  Won't Fix
Status in ubuntu-meta package in Ubuntu:
  Fix Released

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
