I have turned HTT and auto powermanagement off in bios (system cannot sleep), lowest cpu acpi state is C1. Here is dmesg: bge0: mem 0xf3be0000-0xf3beffff,0xf3bf0000-0xf3bfffff irq 17 at device 0.0 on pci6 bge0: CHIP ID 0x05761100; ASIC REV 0x5761; CHIP REV 0x57611; PCI-E miibus0: on bge0 brgphy0: PHY 1 on miibus0 brgphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-master, 1000baseT-FDX, 1000baseT-FDX-master, auto, auto-flow Here is pciconf -lv: bge0@pci0:6:0:0: class=0x020000 card=0x026d1028 chip=0x168114e4 rev=0x10 hdr=0x00 vendor = 'Broadcom Corporation' device = 'Broadcom 57XX Gigabit Integrated Controller (BCM5761)' class = network subclass = ethernet here is the setup in rc.conf: ifconfig_bge0="polling -tso -vlanhwtso -vlanhwtag -vlanmtu inet 192.168.123.124 netmask 255.255.255.0" I have the card plugged into a dlink DSS8 100mbps switch with one other 100mbps device on it (rich man's crossover cable). Before turning off TSO4 and VLAN tagging (because I don't use them), the card would do several things: 1. 1 out of 3 reboots: Fail to bring interface up. ifconfig would hang and systat/vmstat showed 800+ interrupts per second on IRQ256 2. After a few hours lock up the system, requiring hard reboot After disabling TSO4 and VLAN stuff: bge0: flags=8802 metric 0 mtu 1500 options=80083 media: Ethernet autoselect (100baseTX ) Everything seemed fine for about two weeks and then suddenly started acting up again, locked up, after hard reboot, soft reboot, link will not come up and I see interrupt storm again.... I am close to buying an intel card to replace the bcm, but then I noticed that the main intel desktop PCI-E card is 82574L-based and people are having em driver wedging on that too. So now I have broken ethernet on this box; my primary link is atheros 5212 pci card and I may be out of pci slots (or else I might try a pci intel card).
