There are a couple of weird issues so I list in order - With the Jan snapshot the kernel only see the DVD Drive that the CD was booted in - but it cannot later on when sysinstall is running use the drive but gives read errors So I installed the system from a spare USB CD Drive - When I boot the system normally it does not find any SATA DVD's at all - atacontrol comes out blank - However if I boot from a DVD drive with unload Rootdev=disk0s1 Currdev=disk0s1 The atacontrol can see the opposite drive to the one I booted from. So I CVSUP'ed and got the kernel up to date and here what happens I am still booting from the DVD Drive but running the systems of the internal disk and here the funny thing. The kernel can see one drive - However if I detach that CD and detach the empty SATA channel where the other CD are I can attach any one of them - but not at the same time See the atacontrol for the sequence - I can make the kernel panic - if I have one drive attached and detach the other channel and try to reinit it the kernel panics with a mutex error in ata-queue - unfortunately I done have a kernel dump Regards Thomas ------=_NextPart_000_0021_01C74E49.58F419C0--
