Ok, another problem that I was abviously hit by, causing 5 is the so |
| 23 |
called <interrupt>915@pci - bug which never hit my before, but now it |
| 24 |
does with any driver version. |
| 25 |
It can be seen when DRI is enabled using powertop that the i915 module |
| 26 |
is generating A LOT of interrupts slowing down the system, maybe the |
| 27 |
memory usage is just normal since I acutally never checked that before I |
| 28 |
had problems. |
| 29 |
I was pointed at the problem on lesswatts.org |

The fundamental theorem of algebra is open source. Like any other |
| 242 |
mathematical theorem it can be applied free of charge and everybody |
| 243 |
has access to its proof and can convince himself how it works. Why |
| 244 |
should software be any different? |
