Cannot boot a software raid array with 'generic' kernel (Slackware 12)


I've managed to install Slackware 12.0 on a VMware virtual machine.
It boots fine using the 'huge' kernel but I cannot boot with the
'generic' kernel.
I've made an initrd image with the following command:

mkinitrd -c -k -m sg:mptbase:mptspi:mptscsih:dm-mirror:dm-
multipath:ext3 -f ext3 -r /dev/md0

... and this is what I've got:

I don't have any experience with software raid, but are you sure your root needs to be /dev/md0 ? It is failing to mount /dev/md0

It might be /dev/md/0 from what I've seen of Slackware 12.
