I expected it to report a DMA error, but I did not expect it to hang.  Turns out, the “wd” code just retries the request on a DMA error.  That seems to be not a very smart idea, but maybe it’s a good thing to do on some systems?  Anyway, I will add some additional error codes so that “wd” can correctly determine that this error is fatal and a retry should not occur.
