[Bug 1815788] Re: lshw exits with segmentation fault when commissioning a new node on maas

[Tom Mercelis]

We are a few versions further, of everything, but I'm still having
issues with (nearly identical) HPE Bl460gen7 hosts, some of which fail
on the lshw step, others don't. Did anyone get an insight on how to
solve this? Or work around it?

Title:
  lshw exits with segmentation fault when commissioning a new node on
  maas

Status in MAAS:
  Invalid
Status in lshw package in Ubuntu:
  Expired

Bug description:
  Commissioning of new nodes on maas fails due to segfault in lshw, more specifically in 00-maas-01-lshw step.
  The log output is 
  /tmp/user_data.sh.9Xnacy/scripts/commissioning/00-maas-01-lshw: line 6:  2514 Segmentation fault      sudo -n /usr/bin/lshw -xml

  lshw exits with Segmentation fault even if launched directly from the
  shell

  ubuntu at model-seal:/var/crash$ sudo lshw
  Segmentation fault          
  ubuntu at model-seal:/var/crash$ 

  However the same command works correctly if launched with --disable
  SCSI option

  The environment is the ephemeral stage of maas 2.4 with ubuntu 18.04.2
  LTS
