X log from vanilla kernel
Just noticed that for whatever reason my bootloader decided that if it can't
load kernel it will just load another one... vanilla for real this time

Does this happen if you don't do any reclocking? If so, let's get reclocking out of the picture. If not, you could try a newer kernel, but I think in general, reclocking isn't really supported (you probably noticed that you had to add a special parameter to get it to work, that's not a coincidence). I think some work is currently being done for the NVA3+ cards, you could try to find out status in #nouveau on freenode if you're interested.

| Resolution | --- | WONTFIX |
Reclocking is presently not supported. We know it kills many different cards for many different reasons. Closing as WONTFIX. (Not that it'll never get fixed, just not worth keeping this bug open for a presently-unsupported feature.) When/if we get good reclocking support, and you still have issues, feel free to reopen. [It appears that you're seeing mem faults, and reclocking memory is one of the buggiest parts of the current reclocking logic. Makes sense.]
