 Hello!
 
 I just experienced something very similar with an Asus P5B/intel with an
 on-board Realtek PCIe Ethernet, with telnet(1) and ftp(1) on

 for me, the symptoms disappeared by removing -rxcsum and -txcsum from the
 interface. Maybe this is a work-around.
 
 For reference, comparison was against a 3com 3c905tx PCI (xl0) in the same
 machine, configured identically ( same IP number, same local network ) on an
 alternate boot. The remote system in both cases was an ancient RELENG-3 testbed.
 Note that connecting to remote RELENG-6 systems did not exhibit the problem
 hangs with rxcsum/txcsum enabled. All test traffic traversed a RELENG-6
 natd/ipfw gateway. No connections to hosts on the same LAN showed hung behavior
 ( but there are no pre-RELENG-6 boxes to test against on the local LAN at the
 moment ).
 
 Hope this helps.
