[Bug 1610477] Re: memory_compare and get_make_and_model fails on Hitachi CB500 due to lshw issues

[Jeff Lane]

OK, this isn't a problem with the test tools... I'm not positive if this
is a kernel issue, or a lshw issue, but thanks to PKs attachments, I've
been able to manually and programmatically parse the outputs for 'lshw
-json' and 'lshw -C system' and both parse correctly and both scripts
work when modified to read the files PK provided.

So this is the issue:

When this system has a USB3.0 device plugged in, lshw segfaults. 
When this system has a USB2.0 device plugged in, lshw does not segfault.

IIRC the USB hub initially used was a USB3.0 Hub with both a USB2.0 and
USB3.0 thumbdrive plugged in.

I would suggest a couple things:

1:  Re-install Trusty (specifically 14.04.5 if not already on that) and see if this is re-creatable.
2:  Install 16.04.1 (Xenial) and see if it occurs there as well.

I've also mentioned all this to Brian.

So the net is I won't block a cert on this issue, as it's a corner case
but I think it does need to be figured out and determined if it's a
bigger issue than just lshw segfaulting (e.g. will more important things
have problems if someone connects a USB3.0 device).
