** Description changed:
lshw on AArch64 hardware is painfully slow.
This affects both lshw in current Ubuntu releases and vanilla upstream.
For a 48 core node, cpuinfo parsing added up to 30 seconds (8 lines
per core in /proc/cpuinfo add up to 384 lines to parse).
For a 96 core nod
Thanks. Process to upload.

Hi,
If it helps, we have an old DEB package at [1].
I think it's based on the lshw version that was used by Trusty or Xenial at
that time.

My 200+ ARM machine fails to commission in MaaS because lshw takes 8
minutes to run. I will try out this patch and see if it speeds up lshw.
