Can you check your messages in the log and post full calltraces (not cut down as this one) here please?

Well, we had some strange issues looking like stack overflows and there are some messages which can be found by google, but had no real confirmation of stack overflows.

The main reason why we switched it back to 8k stacks is that it provides slightly better performance under high load when lots of interrupts are generated and stack switching introduces noticable overhead (2-4%).
