Dear sir/madam,

I'm running Lubuntu 19.04 (64-bit) on a Dell Precision 7510 (with a Nvidia Quadro M2000M GPU).

The Quadro M2000M is governed by:
nvidia-driver-418 418.56-0ubuntu1
nvidia-prime 0.8.10

I've just upgraded to Kernel ver.:
linux-oem-osp1 5.0.0.1015.16

Since upgrading to kernel ver. 5.0.0.1015.16, the Quadro M2000M will not power down, e.g. Powertop shows 100% power usage for the M2000M, even though the "Intel" profile is selected via Nvidia-Prime.

When booting from kernel 5.0.0-1013.14, the Nvidia-GPU will power down just fine.

I'm guessing this problem was introduced by this changeset. I do not know if this problem warrants a new / seperate bug, if so i'm happy to create a new bug.
