Bug Description

Since yesterday, system completely freezes up (mouse, keyboard, open terminal etc freezing, Unity panel clock and ssh still running) shortly after login, with fwupd using 100% CPU. Killing it doesn't do anything, but "sudo pkill bamfdaemon" resolves the freeze-up.
Interestingly, when I tried the first few times to reboot through ssh, it did, but then got hanging at the shutdown screen, only with a hard-reset left as option.
I also tried to boot an older kernel, same issue. Seems another update broke the system.
I will attach my dmesg and syslog, maybe they're useful.

This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'
