Package: linux-2.6
Severity: normal
Tags: patch
In order to use a 2.6.16 linux kernel on our Dell PowerEdge 1600SC with
CERC ATA100/4ch raid controller I had to apply th following patch to the
legacy megaraid driver to support the device.
The new driver (megaraid_mbox) recognized the device, displayed some
info on its configuration, but did not provide the system with any
disks. I guess it does not support CERC ATA100/4ch at all.
