A week ago I upgraded to the latest Ubuntu distribution (Linux thunderbird
4.18.0-10-generic #11-Ubuntu SMP Thu Oct 11 15:13:55 UTC 2018 x86_64 x86_64
x86_64 GNU/Linux).
Whenever I run "shutdown -h now" or "reboot" I receive an immediate kernel
crash with a dump that has:
"Code: Bad RIP value"
What is the best way of collecting and sending information to upstream. I
don't mind learning to build and install the kernel if that will help debug
this.

I Canonical response noted the following from the dump:
[ 42.640541] resource sanity check: requesting [mem 0x000c0000-0x000fffff],
which spans more than PCI Bus 0000:00 [mem 0x000c0000-0x000dffff window]
I've since updated to the latest BIOS at there suggestion.
I see the following on the screen when the kernel crashes:

The newer kernels (like 4.18) have checks regarding copies to userspace for
unwanted kernel memory exposure.
The check fails here. This particular copy was initiated by the binary nvidia
driver, so unfortunately we cannot help here. So either ask Nvidia for a fix
or (if that driver was installed with the Ubuntu software updater) Canonical.
