To wrap up my previous couple of comments and hopefully bisect the problem, I can state the following (thanks to BTRFS):
This problem didn't / does not exist with: Description: Ubuntu Yakkety Yak (development branch) Linux acer07 4.8.0-21-generic #23-Ubuntu SMP Tue Oct 4 18:27:25 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux ii nvidia-304 304.131-0ubuntu5 amd64 NVIDIA legacy binary driver - version 304.131 This problem exists with: Description: Ubuntu 16.10 Linux acer07 4.8.0-26-generic #28-Ubuntu SMP Tue Oct 18 14:39:52 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux ii nvidia-304 304.132-0ubuntu1 amd64 NVIDIA legacy binary driver - version 304.132 Sorry, I don't have any more intermediary points. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-304 in Ubuntu. https://bugs.launchpad.net/bugs/1634802 Title: Could not insert module Status in nvidia-graphics-drivers-304 package in Ubuntu: Confirmed Bug description: Ubuntu release: 16.10 Yakkety Yak Kernel version: 4.8.0-22-generic x86_64 Package version: 304.132-0ubuntu1 The nvidia module cannot be loaded. The following errors are reported: Could not insert module Unknown symbol in module and: nvidia: Unknown symbol mtrr_del (err 0) nvidia: Unknown symbol mtrr_add (err 0) It looks like the buildfix_kernel_4.3.patch, which is supposed to be dealing with those calls, is not applied in this release of the package. The package was working fine with the previous fully updated Ubuntu version 16.04 prior to the upgrade to 16.10.
