WRITE_DMA failures on 5.3 (but NOT on 4.10)

[craig]

as much as i have tried, i have still not managed to resolve this issue.
the best i can do at this time is to revert back to 4.10-stable (which has
its own USB issues...)

considering this is a fairly serious issue (at least, to me it is), would it
be appropriate to post a PR?
i have done a cursory search through the archive and not come up with
anything similar.

thanks,

there wasn't reboot since last, when i turned dma off and i have no strange
messeges in logs..but i have to remind you, that the box froze after 9 days
of uptime, when i had dma turned on, so...

try to turn it off in system before boot in loader prompt
(not sure if this is possible:))

i think so, but there are people who understands this more than me ;-)
