I'm having a strange problem on my Q6600 that cropped up starting with |
| 2 |
the 2.6.29 series of the kernel, and is still present in 2.6.30. |

Essentially, at all times, I have four nice 19 processes running, which |
| 5 |
for the sake of this post, we'll call "dnetc". All four cores are |
| 6 |
utilized. At this point, if I start another CPU-bound process that isn't |
| 7 |
niced, it begins to take up an entire core. This is expected. What isn't |
| 8 |
expected, however, is that another core begins idling inexplicably. As a |
| 9 |
result, despite 5 processes currently available to run, only 3 are |
| 10 |
actually running at any given time (the non-niced process, and two |
| 11 |
instances of dnetc). |

I have no idea where to begin diagnosing this, so if anyone has any |
| 14 |
pointers or knows anything, I'd like to hear about it. I've done numerous |
| 15 |
searches of mailing lists, bug trackers, etc., but haven't found |
| 16 |
anything. Maybe I just can't find the right keywords. |
