This could be. I currently have 3 U1's running 2.6.15-r5 perfectly |
| 21 |
fine. I'm still sort of in the process of building them out (just |
| 22 |
adding packaged I need and such), so they have been compiling (with |
| 23 |
distcc) fine for about 3 days straight. Two are 200Mhz Ultrasparc I's |
| 24 |
and one is a 166Mhz U1. |
| 25 |
|
| 26 |
They each only have one processor, but SMP is enabled. |
