Hi Tomas,

So far the problem has only been a one off thing for me, so it would
seem that whatever circumstances contributed to it are fairly rare, but
unless the underlying issue has been identified and fixed I would not
recommend just dropping the patch. When it did hit I ended up with my
log files (kern.log, syslog & messages) filled up with 15GB of the
messages mentioned in the commit message within minutes, until my hard
drive ran out of space bringing my system down.

Even if the underlying issue is fixed I do not see any advantage in
dropping the rate limit patch - it is an absolutely trivial* patch, and
if anything I would expand it to cover all the error messages in the
driver, not just the three involved in that particular case.

* It's essentially: sed 's/dev_\(warn\|err\)\>/dev_\1_ratelimited/g'
