That's a bug in the kernel, so my first step would be to try the most recent |
| 17 |
kernel, hoping that the bug has already been fixed upstream. If the most |
| 18 |
recent kernel crashes the same way, then I would try older kernels, hoping |
| 19 |
to find where the bug first appeared. |

The word "Tainted" refers to your nvidia driver (see below). Some kernel |
| 24 |
developers may refuse to accept a bug report if they see the word "Tainted", |
| 25 |
but I've never had a bug report refused for that reason. You can get rid |
| 26 |
of the "Tainted" by using an open-source driver like nouveau or the old 'nv' |
| 27 |
if you have trouble getting a bug report accepted by a kernel developer. |
