| 210 | G3 and G4 processors have an on-chip temperature sensor called the |
| 211 | 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die |
| 212 | temperature within 2-4 degrees Celsius. This option shows the current |
| 213 | on-die temperature in /proc/cpuinfo if the cpu supports it. |
| 214 | |
| 215 | Unfortunately, on some chip revisions, this sensor is very inaccurate |
| 216 | and in many cases, does not work at all, so don't assume the cpu |

| 227 | |
| 228 | However, on some cpus it appears that the TAU interrupt hardware |
| 229 | is buggy and can cause a situation which would lead unexplained hard |
| 230 | lockups. |

| 242 | either changing a lot, or the TAU hardware is broken (likely on some |
| 243 | G4's). If the range is small (around 4 degrees), the temperature is |
| 244 | relatively stable. If you say Y here, a single temperature value, |
| 245 | halfway between the upper and lower bounds, will be reported in |
