Lshw In CentOS 7

I’ve been running lshw for years in both CentOS 6 and CentOS 7, yet just recently it started hanging. Neither a Control^C nor a “kill”
of the process cured the hang; only a reboot.

When I run it by hand from the command line, it displays stuff on the next line overwriting it with things like PCI, USB. And USB is the last thing I see. A Control-C does not unlock it.

I am running lshw-B.02.18-7.el7.x86_64. The CPU is an Intel I7-3770K, running CentOS 7.4.1708

Is there any idea? Is there some alternate program that could list the hardware?

  • Is this just one system or a range of boxes? I just ran it on 2
    different ones running CentOS 7 and it worked fine there. If it is just one particular hardware then look through the lshw man page and try the versions of something like

    lshw -disable usb

    to see if it still happens. [It might require other tests also.]

    You could also try running it via strace – it might give you a clue as to where it is hanging :

    strace -f lshw
