Hi all,

I got the following when I tried to create raid1 over nine sata disks.
One on onboard NVidia and eight on a Promise SX8.

Both the motherboard (Tyan K8SE) and the Promise SX8 are flashed with
the latest bios, FWIW.

NCQ is disabled in the Promise controller (although the current firmware
should be able to handle it).

OS is up to date Debian Sid in an initramfs which I use to install the
system.

Please let me know if this is of any use, if so, whom I should contact,
and if more info is needed.

Btw, this system is fresh out of the box, so hardware can be a problem
too.

I'll try plain 2.6.15 now.

	Kind regards, Sander

PS, I had to create the /dev/sx8 directory and the nodes (0, 1, 0p1,
1p1, etc) for the disks and partitions by hand (mknod). Is there a more
easy way? It seems MAKEDEV in Debian Sid doesn't know how to. Do I miss
something? (likely, but I did my google homework ;-)
