Yea, since it's doing a poll here you really aren't at risk of a long
delay if it took more than 10 milliseconds, so it's likely an issue
with driver not returning the timestamp, or dropping it or similar.

Definitely upgrading the kernel is the best approach to help reduce
odds that it's a stack bug.
