This is a dual CPU i386 machine. I began with a fresh install of 6.1-RELEASE, discovered this issue, and then CVSup'ed my source to 6.2-STABLE. I've rebuilt the world and kernel and installed both successfully, and ran mergemaster as well. As a side note, the NIC worked fine with i386 5.4-RELEASE. When the machine comes up, the interfaces stay "status: no carrier" until I either type "ifconfig bge0 media 1000baseSX mediaopt full-duplex" or "ifconfig bge0 up". Naturally, I wish to use both NIC's so I enter the same info but replace bge0 with bge1. Setting an IP address and netmask also did not help. Once I type either of those, I get a continuous stream of: bge0: link state changed to UP bge0: link state changed to DOWN bge1: link state changed to UP bge1: link state changed to DOWN bge0: link state changed to UP bge0: link state changed to DOWN bge1: link state changed to UP bge1: link state changed to DOWN .. forever. I also get an intermittent statement: bgeX: 2 link states coalesced This will occur until I shut down the interfaces with "ifconfig bge0 down" and "ifconfig bge1 down" statements. I have rebuilt my kernel with "BGE_FAKE_AUTONEG" and added ' hw.bge.fake_autoneg="1" ' to the /boot/loader.conf which resulted in no noticable effect. sysctl maintains that this oid does not exist, and sysctl -w does not show any entry related to hw.bge* -- It would be nice to be able to see if this is actually being set or not. I've added and removed SMP support, added and removed DEVICE_POLLING and various combinations with and without APIC. I've also gone back and forth between booting with ACPI and without ACPI, again, without a noticable effect on the issue. I tried merging the device drivers in from HEAD, but as I expected, that was futile :) If necessary, it may be possible for me to provide a 3com 3c996-SX NIC to help fix this issue. >How-To-Repeat: Get a 3Com 3c996-SX nic, and try to use it on FreeBSD 6.2-STABLE or -RELEASE. >Fix: Don't use a 3com 3C996-SX with FreeBSD 6.2. Try using FreeBSD 5.4 -- the Interface worked fine then. I did not try using 5.5. >Release-Note: >Audit-Trail: >Unformatted:
