Agree, it's better course of actions.

Mentioned patch fixes fastboot. Now it works as expected. The only new
thing I noticed (which appeared after applying that patch) is next
message (showed after running "fastboot 0" command):

    UNKNOWN IRQ type 1683973225

It's harmless though, fastboot works as expected. So I presume we
should merge that DMA patch, as it's obviously useful and fixes real
bug.

Thanks for helping me out :)
