Hello, as reverting this patch fixes this rather annoying problem: is it dangerous to revert it as a workaround until the root cause is found?Unfortunately no, this patch fixes a serious issue. We need to find the root cause of your problem instead of trying to work around it.I only wanted to use it as local workaround here. I looked a bit at at code. I'm not familiar with the network code, though :-).
If it helps, I'm running the reverted patch on five production boxes hitherto without a hiccup. As far as I understood the original commit message, some packet counters might me wrong without it. @Eric: What could possibly go wrong(tm)? :) Of course a real fix is preferred over this band-aid. Cheers, Thomas
