Bug Description

In BIOS all CPU cores enabled, in gnome-system-monitor I can see 4 cores, but lshw displays enabledcores=1 (dmidecode displays same information, as lshw). Also lshw says cache:2 DISABLED, but it is not disabled in BIOS.

I've noticed the same thing on Ubuntu 20.04.
That is, 4 cores but reports only one enabled -- even when they are all "working hard".

Also,
sudo lshw -version
just reports a "blank line", no version number.

The installer says that I have lshw version
02.18.85-0.3ubuntu2.20.04.1

HTH

I've checked, and same issue on Ubuntu 18.04.5 (i.e cores=4 enabledcores=1)

BUT, good news, at least there
lshw -version
reports a version: B.02.18
and, yes, it is a 'B'?!

Packager reports lshw as version 02.18-0.1ubuntu6.18.04.2
