It appears that lshw is blocking on an input/output (I/O) operation
related to a virtual network interface, specifically /dev/vmnet1, which
is often associated with VMware. This could indicate a problem with the
virtualization module or permissions related to that interface.
the command sudo /usr/bin/lshw -class network does not work either
sudo strace lshw :
readlink("/sys", 0x7fff674c6210, 1023) = -1 EINVAL (Argument invalide)
readlink("/sys/class", 0x7fff674c6210, 1023) = -1 EINVAL (Argument invalide)
