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
