I knew about the wdattach() bug, but thought that it was unimportant because wdreset() doesn't get called except for error handling. Of course, errors are likely when the interface is screwed up. The driver has some support for falling back to PIO mode after certain errors. I've never seen that work. Timeouts are very generious so I would expect it to take several minutes at best. It only does it for aborted commands, and there is no provision for getting back to DMA mode if the error wasn't for DMA.
