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: port 0x3040-0x307f mem 0xd8320000-0xd833ffff irq 54 at device 2.0 on pci3 em0: Ethernet address: XXXXXXXXXX em0: [FAST] em1: 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 mtu 1500 options=b inet 1.2.3.4 netmask 0xffffff00 broadcast 1.2.3.4 ether XXXXXXXXX media: Ethernet autoselect (100baseTX ) status: active Hope this helps to narrow down the problem.
