I'm not sure whether you're seeing the same bug not handled in the workaround code, though. If you disable Rx checksum offloading(e.g. ifconfig ale0 -rxcsum) does ssh still complain 'corrupted MAC'? Since you seem to have a way to reproduce the issue, would you show me the way to trigger the issue? > thank you very much for any suggestions > > giuseppe
