That's a bug in the kernel, so my first step would be to try the most recent
kernel, hoping that the bug has already been fixed upstream. If the most
recent kernel crashes the same way, then I would try older kernels, hoping
to find where the bug first appeared.

The word "Tainted" refers to your nvidia driver (see below). Some kernel
developers may refuse to accept a bug report if they see the word "Tainted",
but I've never had a bug report refused for that reason. You can get rid
of the "Tainted" by using an open-source driver like nouveau or the old 'nv'
if you have trouble getting a bug report accepted by a kernel developer.
