[Bug 2069649] Re: lshw hangs running forever at Network Interfaces CLASS

[olive]

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)
readlink("/sys/class/net", 0x7fff674c6210, 1023) = -1 EINVAL (Argument invalide)
readlink("/sys/class/net/dev", 0x7fff674c6210, 1023) = -1 ENOENT (Aucun fichier ou dossier de ce nom)
access("/sys/class/net//dev/vmnet1/device", F_OK) = -1 ENOENT (Aucun fichier ou dossier de ce nom)
readlink("/sys", 0x7fff674c62a0, 1023)  = -1 EINVAL (Argument invalide)
readlink("/sys/class", 0x7fff674c62a0, 1023) = -1 EINVAL (Argument invalide)
readlink("/sys/class/net", 0x7fff674c62a0, 1023) = -1 EINVAL (Argument invalide)
readlink("/sys/class/net/dev", 0x7fff674c62a0, 1023) = -1 ENOENT (Aucun fichier ou dossier de ce nom)
openat(AT_FDCWD, "/sys/class/net//dev/vmnet1/modalias", O_RDONLY) = -1 ENOENT (Aucun fichier ou dossier de ce nom)
socket(AF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
ioctl(4, SIOCGIFADDR, {ifr_name="/dev/vmnet1"
