Please pardon my "jumping in" and/or ignorance...

ed0 living on an IRQ that is "reserved" (somehow) for one
of the ATA "channels?"  (ie. 14 and/or 15?)

Hmmm...  I might "question" an ATA-probe "there..."  (?)

Can this card (ed0) go to a different IRQ?  Is that IRQ
disabled/reassigned (from PCI) in the BIOS/setup?

>  device          ed1     at isa? port 0x340 irq 9 iomem 0xd8000

I might want to "move" this one, too; IRQ 9 is the "shared"
one & it has always "frightened" me some...  :)

(Brain-cobweb-digging)  I also notice that that the "iomem"
is the same; shouldn't those be different segments?

Hope I was at least slightly helpful...
