440.59-0ubuntu0.19.10.2 DKMS Build Fail on Kernel 5.6-rc4

[berglh]

I'm running an AMD Ryzen 3000 processor and I'm looking forward to the k10temp module updates in 5.6 to expose more metrics from the CPU to the system for monitoring. (vCore, temperature per CCD, etc).

At the moment, the only thing keeping me from using this RC is the build fail for nvidia DKMS. I can guess that as a release candidate my mileage would vary. I just noticed in the build changes that some features should support 5.5+, so I thought I would try it out.

Attached is the DKMS build log error for reference.

I noticed a new release by @~ricotz, thanks for addressing this so quickly!

    - Fixed driver installation failure on Linux kernel 5.6 release
      candidates, where the NVIDIA kernel module failed to build with
      error "implicit declaration of function 'ioremap_nocache'".

I'm still getting a DKMS build failure, log is attached for reference.

Looks like it might be related to gcc version used to build? Here are my package versions:

ii gcc 4:9.2.1-3.1ubuntu1 amd64 GNU C compiler
ii gcc-9 9.2.1-9ubuntu2 amd64 GNU C compiler
ii gcc-9-base:amd64 9.2.1-9ubuntu2 amd64 GCC, the GNU Compiler Collection (base package)
ii gcc-9-base:i386 9.2.1-9ubuntu2 i386 GCC, the GNU Compiler Collection (base package)
ii libgcc-9-dev:amd64 9.2.1-9ubuntu2 amd64 GCC support library (development files)
ii libgcc1:amd64 1:9.2.1-9ubuntu2 amd64 GCC support library
ii libgcc1:i386 1:9.2.1-9ubuntu2 i386 GCC support library

Status changed to 'Confirmed' because the bug affects multiple users.

Great! That version is in proposed so we call that Fix Committed. And on that note, since there was no 440 driver released for Ubuntu 19.10 yet we really shouldn't have been discussing it here. But it's resolved anyway.
