 | 448 | 	  to get notified the temp has exceeded a range. With this option off, | 
 | 449 | 	  a timer is used to re-check the temperature periodically. | 
 | 450 |  | 
 | 451 | 	  However, on some cpus it appears that the TAU interrupt hardware | 
 | 452 | 	  is buggy and can cause a situation which would lead unexplained hard | 
 | 453 | 	  lockups. |

 | 465 | 	  either changing a lot, or the TAU hardware is broken (likely on some | 
 | 466 | 	  G4's). If the range is small (around 4 degrees), the temperature is | 
 | 467 | 	  relatively stable.  If you say Y here, a single temperature value, |
