Bug description:
  This is with MAAS 2.7.0, commissioning an HP DL385 G7 with Bionic.
  During the first boot, the machine performs an apt-get upgrade, which 
includes an update of ipmitool (1.8.18-5ubuntu0.1) and freeipmi-tools 
(1.4.11-1.1ubuntu4.1).
  This triggers hung tasks:

  I can perform more tests on this system if needed.
