What is your kernel version? (could be important). |

I'm using 2.7.11 on kernel 2.6.16, write performance is reasonably good |
| 22 |
- 100 Mb/s on a 4 disk raid0 array (in fact I could probably do better |
| 23 |
if the promise driver would let me run the disks at udma5 instead of |
| 24 |
udma6....) |
