I have an express-card interface which randomly decides to stop talking:

Nov 21 09:22:29 toshi kernel: re0: <RealTek 8168/8111 B/C/CP/D/DP/E/F
PCIe Gigabit Ethernet> port 0x2000-0x20ff mem

Nov 21 09:22:29 toshi kernel: re0: Ethernet address: 00:0a:cd:1d:30:a2

After an indeterminate period, it logs ..

Nov 21 09:23:33 toshi kernel: re0: PHY read failed
Nov 21 09:23:39 toshi last message repeated 24 times

Any thoughts as to how to troubleshoot/fix?
