interface mysteriously renamed

I'm seeing a very strange bug and I wanted to throw it out on the list
before trying to file it:

My network interface decided that it was eth2 today.  It used to be
eth1 but it looks like now it thinks it's eth0 and then it jumps up to

# dmesg |grep e100
[17179600.880000] e100: Intel(R) PRO/100 Network Driver, 3.4.14-k4-NAPI
[17179600.880000] e100: Copyright(c) 1999-2005 Intel Corporation
[17179600.904000] e100: eth0: e100_probe: addr 0xd0500000, irq 66, MAC
addr 00:08:C7:6B:EA:5D
[17179824.740000] e100: eth2: e100_watchdog: link up, 100Mbps, full-duplex

I have another interface which may partly explain the problem I guess:
# dmesg |grep sky
[17179600.964000] sky2 v1.4 addr 0xff620000 irq 177 Yukon-EC (0xb6) rev 1
[17179600.964000] sky2 eth1: addr 00:11:11:47:5d:57

but I don't use that interface because the driver doesn't appear to be
very stable yet.

Any ideas what's going on or how to control it?
