Status changed to 'Confirmed' because the bug affects multiple users.

Also on 24.04, lshw version is also the same.

Here's the tail of "sudo strace lshw" (yes strace freezes and doesn't finish printing the line):

vmnet1 is an interface for VMware Workstation Pro 17.5.2 with modified kernel modules from https://github.com/mkubecek/vmware-host-modules/tree/workstation-17.5.1 that work with newer kernels.

I'm curious if Carlos is also using Workstation pro with those kernel modules.

Curious where strace stalls for Carlos: sudo strace lshw 2>&1 | tee -a /tmp/out
