Hi,

I successfully installed Dragonfly on my laptop and compiled a new
kernel. However, when booting the new kernel panics: can't find boot
device 'ad' (root is on /dev/ad0s1a). There is no 'ad' in the list of
devices recognized by kernel. ata0 appears in the boot messages
though. The nata devices are all present in my kernel config file,
precisely as in GENERIC. What might be wrong?
thanks, Must

Can you boot from the original install media, see what it recognized for 
the ATA controller and attached device(s) - then do the same with the 
one with the new kernel - at least as much as you can see.

I'd say you compiled w/o a needed driver except that it sounds as if you 
aren't even getting to where the boot loader can *find* that kernel and 
its drivers.

What did you change for your new kernel?

Bill
