Crash with kernel 4.5 and 4.6

Can’t run latest Nvidia drivers with kernels 4.5 or 4.6 (Fedora).
Get a memory dump even with a vanilla kernel.

Ssh with a remote machine give this dump:

Thank’s

Same problem here, Did not try with 4.6, but starting from 4.5 it crashes same way here. I use Precision M4600 laptop with Quadro 2000M (F23)

For now I workaround this using a crude hack:

Ugly like hell, but as this path (this == IS_VGX_HYPER) is not using SetPageReserved() (defined as NV_LOCK_PAGE) and this call seems to trigger this assert it works until someone figure something more correct.

Thanks for your hack.

I’m wondering if it’s a fedora config problem cause other users don’t complain with this kernel.
(http://rglinuxtech.com/?p=1647).
I filed a bug a bug to fedora two months ago but they said “No support for this driver see with Nvidia”
Sorry for my english.

Quick check and it seems disabling CONFIG_DEBUG_VM_PGFLAGS prevents problem from happening (obvious) but the question is where the problem is …in kernel or in nvidia drivers ? I hope someone from nvidia dev’s will clarify/check that.

Please attach nvidia bug report and kernel config file.

It looks like the change in 4.5 is affecting more than just the nVidia driver:

https://www.virtualbox.org/changeset/60372/vbox
https://bugzilla.redhat.com/show_bug.cgi?id=1307033
https://bugzilla.redhat.com/show_bug.cgi?id=1317296

Internally filed bug to track this issue : Bug 200189979

When I recompile the kernel without CONFIG_DEBUG_VM_PGFLAGS I got the nvida driver to work without patching.

Fedora’s bug is being tracked here: https://bugzilla.redhat.com/show_bug.cgi?id=1335173
