Hello,

I have a Dell XPS 15 9560 with a GTX 1050 Mobile (GP107M) and an Intel Kabylake CPU. Using Kernel 4.11.3 on the Arch installer image, whenever I run 'lspci', it blocks indefinitely and never prints any output.

After running lspci, dmesg contains:

[ 54.819264] nouveau 0000:01:00.0: Refused to change power state, currently in D3
[ 54.879968] nouveau 0000:01:00.0: Refused to change power state, currently in D3
[ 54.879973] nouveau 0000:01:00.0: Refused to change power state, currently in D3
[ 54.879974] nouveau 0000:01:00.0: DRM: resuming object tree...

Eventually the scheduler gets cranky about the hung process and starts spewing
[ 245.385522] INFO: task lspci:576 blocked for more than 120 seconds.
and a backtrace every 2 minutes.

Blacklisting nouveau makes lspci work.
