[workaround] lspci hangs indefinitely

Hi,

when I run lspci there is no output and the process will use 100%  of one CPU core.
The process cannot be killed with SIGTERM nor with SIGKILL
There is no lspci output even with -vv switch.

When I shutdown the machine, systemd starts to complain about a process it cannot kill and I have to use the power button to poweroff.

These are the only errors in the journal:

Re: [workaround] lspci hangs indefinitely

Blacklisting the nouveau module solves this problem.

Re: [workaround] lspci hangs indefinitely

This thing just happened to me on an MSI GE62 6QD laptop, and this thread saved my day. I know this is an old thread, but I just wanted to add my laptop model here so hopefully people looking for it on a search engine will find what the problem is. This was also the cause of my Xserver failing to start.

Re: [workaround] lspci hangs indefinitely

This one saved me too, also from the issues with the X server not starting. Thanks!!

Edit:: I'm on an ASUS F550V in case it helps anyone else.
