Hello,

my network card is failing - dmesg is full of this:

re0: PHY write failed
re0: reset never completed!
re0: reset never completed!
re0: PHY write failed
re0: reset never completed!
re0: PHY write failed
re0: link state changed to DOWN
re0: link state changed to DOWN
re0: reset never completed!
re0: link state changed to DOWN
re0: link state changed to DOWN

It can work nicely for days (although the server is not yet in production, so there
is little to no traffic) and then starts failing. What could be the problem?

It's FreeBSD 7.0 with this card:

re0@pci0:4:1:0: class=0x020000 card=0x816910ec chip=0x816910ec rev=0x10 hdr=0x00
     vendor     = 'Realtek Semiconductor'
     device     = 'RTL8110SB Single-Chip Gigabit LOM Ethernet Controller'
     class      = network
     subclass   = ethernet

"ifconfig re0":

re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
         options=399b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
         ether 00:0e:2e:cc:1e:c9
         inet 192.168.2.10 netmask 0xffffff00 broadcast 192.168.2.255
         media: Ethernet autoselect (1000baseTX <full-duplex>)
         status: active

The hardware is a PC with Asus P5K-SE motherboard.

Thanks,
Nejc
