--- Comment #8 from Martin Birgmeier <d8zNeCFG@aon.at> ---
An update after a while: It seems the culprit is net/realtek-re-kmod198, which
I need for this motherboard.

For some reason, in normal operation one does not notice issues, but with iSCSI
it does not work. Recently I needed this machine to be an iSCSI client instead
of a server, and the data was corrupted in a similar manner.

I should follow the advice given by Jordan in comment #5 and enable the iSCSI
digest algorithms. However, for now I have instead added "-rxcsum -txcsum
-rxcsum6 -txcsum6" to the ifconfig lines (IPv4 and IPv6) for this interface in
/etc/rc.conf. I have yet to try again with iSCSI in this manner.
