so now you go from an occasional burp to having nothing at all.
How about you run with this patch on your own machine only?

or.. since you say a reload of the driver fixes it.. why don't you make
a patch for the driver that does basically the actions of a reload
automatically when the driver detects the issue?
(and stick a WARN_ON in for good measure so that can
start tracking these burps)
