We have several dual cpu systems - half intel, the other half AMD. |
| 2 |
For our purposes, we are building to the i686 arch. |

The hosts with the below described problem are running on Tyan mother boards with LSI Logic SCSI controllers embedded in PCI-E bus. |

|

We rescently upgraded to the 2.6.15-r1 kernel and life is great on the systems that use the adaptec scsi controllers. However, LSI Logic does not appear to be seen by udev or, more likely, initramfs facilities. Consequently, no root device is found. |
