    I agree with what archangel.amael said, that its not a bug or fix.

    First off, its not a bug because that's how linux detects the devices. Whichever device first pops up in the probing and the driver is loaded, gets the preference of using the very first interface number.

    Say for example you have intel e1000, and intel ipw2200 on the same computer. Both of these drivers use the same interface naming.. ethX (where X is the number for the device). At times when you boot up you get e1000 as eth0 but other times its ipw2200 as eth0 and usually the versa device ends up using eth1 instead of eth0.

    It is either that or it can be an udev issue (not common on backtrack). There are workarounds, one is the alias the alternative interface as some other name or if the chipset has another driver, I'd give that a go if the alternating interface numbering is bugging you.

    It is not a fix because you didn't provide a fix :P
