So, I guess its David and Herbert's turn?...

If you're bored in the meantime I'd suggest to do check the realtek
driver eg:
- for locking with the patch below,
- to turn off with ethtool its tx-checksumming and/or scatter-gather,

After rethinking, it's almost impossible this patch could change
anything here, so don't bother, but consider mainly the second
proposal.

Indeed ;)

Its true that not many nics use the skb_copy_and_csum_dev() helper,
maybe this one must be updated somehow ?

Yes, it seems it should be possible at least to handle the bug with
a warning and error return, considering Plamen's problems with getting
the trace.
