Hi. I've posted some test with the latest em driver in the previous thread "= Proposed 6.2 em RELEASE patch"... It's working fine. Now i see some strange behavior. Machine is Dual Intel Xeon 5110, with = SuperMicro X7-DBE mainboard. It has dual port integrated Intel PRO/1000 = EB lan card, one Intel 82542 Gigabit Ethernet Controller, and one Intel = PRO/1000 PT. The problem is the Intel PRO/1000 PT card. All other cards are in use (i= n production mode), only this card is down and not used right now, but i= t's generating more interrupts than any other card. em3: flags=3D8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500 options=3Db<RXCSUM,TXCSUM,VLAN=5FMTU> ether 00:15:17:0e:10:90 media: Ethernet autoselect status: no carrier output from systat -vm (interrupts/irq/interface): 14235 16: em3 6214 18: em0 914 19: em1 13613 24: em2 currently it has around 200Mbit/s total bandwidth on the other cards system is: FreeBSD 6.2-PRERELEASE #1: Tue Nov 14 17:24:17 EET 2006 amd64 EM=5FINTR=5FFAST is defined in em driver no polling Any clues=3F =5F=5F Miroslav
