I had a lot of such problems with 7.1.9 on my 82566DM, and I thought, that new driver is Ok, but yesterday it happens again with 7.2.3. No packets could be sent, buffers are overfilled, only full reset helps (after "ifconfig wm0 down && ifconfig em0 up" ping starts to report "Host is down" for any remote host, instead of "No buffer space available")... 8-STABLE, 7.2.3 driver, amd64, 82566DM LOM chip. --=20 // Black Lion AKA Lev Serebryakov
