Comment (by hnyman):
I already posted to #14035, as the stack trace there matches my error, but
I suspect that changes made by r42328 may be the reason for errors that
have now surfaced with my wndr3700v2. I don't remember seeing errors with
earlier builds upto 42886, and r42328 is roughly the only significant
driver change since that.
