Well, I don't know but the error message should be improved regardless
by splitting it on separate messages for separate error conditions
(wrong length vs wrong addr).

Lets just make it something like:

"%s: unsupported DRQ type (0x%02x)\n"

"%s: wrong packet size (0x%02x)\n"

We even know the device name so:

"wants to issue more IRQs in DMA mode\n"

should suffice.

I guess that by "Sigh" you meant:

"while issuing a packet command" should go away

;)

"DRQ isn't asserted\n" should be enough here

Seems like most (all?) other error messages can be improved in similar way.
