modprobe nvidia fails after suspend/resume cycle

[Rocko]

My hyrbrid intel-nvidia system is set up to use the intel card by default, and the nvidia card power management is done by the kernel (I run a version of bbswitch that does no power management.)

After a reboot, the nvidia card on my hyrbrid intel-nvidia system is by default suspended by the kernel, but you can enable it by loading the module with "sudo modprobe nvidia". Using bumblebee, I can run programs on the nvidia card via optirun.

However, after a suspend/resume cycle, trying to load the nvidia module fails:

$ sudo modprobe nvidia
modprobe: ERROR: could not insert 'nvidia': No such device

This happens whether I disable bumblebeed.service or not via systemctl. It also happens if I load the nvidia module prior to suspending so the card is active. It also happens whether I'm doing a S0 sleep (mem_sleep = s2idle) or a S3 sleep (mem_sleep = deep).

In Ubuntu 18.10 this wasn't an issue, so it's a regression.
