We have several SMP systems with onboard em0/em1 Interfaces running on a
RELENG_6 snapshot taken at 2006-09-20 00:00+0. They are not in production
yet, so the load is not that much. However I haven't seen any watchdog
timeouts on them. Only annoyance is, that the em(4) interfaces take too long
for the interface to come up, ie, the system will boot, run ifconfig, the
interface still has no link so syslogd/ntpdate/ntpd will complain about 'no
route to host'. A 'sleep 5' fixes that problem, though I'd like to avoid
such hacks.
Anyway, here's the data:
em0@pci3:2:0: class=0x020000 card=0x117a8086 chip=0x10798086 rev=0x03
hdr=0x00
vendor = 'Intel Corporation'
device = '82546EB Dual Port Gigabit Ethernet Controller'
class = network
subclass = ethernet
em1@pci3:2:1: class=0x020000 card=0x117a8086 chip=0x10798086 rev=0x03
hdr=0x00
vendor = 'Intel Corporation'
device = '82546EB Dual Port Gigabit Ethernet Controller'
class = network
subclass = ethernet
em0: <Intel(R) PRO/1000 Network Connection Version - 6.1.4> port
0x3040-0x307f mem 0xd8320000-0xd833ffff irq 54 at device 2.0 on pci3
em0: Ethernet address: XXXXXXXXXX
em0: [FAST]
em1: <Intel(R) PRO/1000 Network Connection Version - 6.1.4> port
0x3080-0x30bf mem 0xd8340000-0xd835ffff irq 55 at device 2.1 on pci3
em1: Ethernet address: XXXXXXXXXX
em1: [FAST]
em0: link state changed to UP
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=b<RXCSUM,TXCSUM,VLAN_MTU>
inet 1.2.3.4 netmask 0xffffff00 broadcast 1.2.3.4
ether XXXXXXXXX
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
Hope this helps to narrow down the problem.
