[Bug 1630711] Re: fwupd using 200% CPU, but status of systemd services is "inactive (dead)"

[Mario Limonciello]

OK thanks.

We have had "some" problems with fwupd and relevant dependencies caused
by corrupted archive metadata.  There have also been some instances of
bad USB devices or bad USB host controllers causing spinning.  When this
happened there was also an associated mess in the kernel log.

For now i'll close it out.  Open it back up if/when it happens again.
Ideally if you could just keep the debug symbols installed that will
make attaching to gdb for figuring out what it's spinning on when this
happens easier.

Title:
  fwupd using 200% CPU, but status of systemd services is  "inactive
  (dead)"

Status in fwupd package in Ubuntu:
  Invalid

Bug description:
  Just hit this, haven't yet dug into details or tried to reproduce it.

  I booted up a nearly up-to-date Yakkety desktop, noticed my fans were
  running like crazy, and looking at top shows `fwupd` is the culprit
  (see attached screenshot).

  I don't know much about fwupd, but I'm guessing it's probably run
  through systemd services. Interestingly, `systemctl status` show
  "inactive (dead)" for the two service files installed by `fwupd`:

  fwupd.service
  fwupd-offline-update.service

  I also checked `fwupdate-cleanup.service` from the `fwupdate` package,
  and it likewise shows "inactive (dead)". So I'm not exactly sure how
  this fwupd process was started, why it's still running.

  Thanks!
