3ware 9650se disks show up as ethx during alternative install

[Bryan McLellan]

I have an amd64 server with a 3ware 9650se controller with 1 RAID-5 and 3 JBODs. In the feisty alternate install (netboot) these disks all show up as /dev/eth2 on this machine (it has two ethernet interfaces on board).

A single sata disk on the on board controller shows up fine as sda. If I install to that disk and boot, the four disks on the 9650se show up fine as /dev/sdx.

The alternative install is running 2.6.20-15-generic, installing linux-image-2.6.20-15-generic after the install does not reproduce the problem.

modinfo on 3w_9xxx reports version 2.26.02.008

The same version of udev (108-0ubuntu4) is provided in the installed deb as in the installer udeb.

3ware controller model 9650se-8lpml, firmware fe9x 3.08.02.005, bios be9x 3.08.00.002

A head-scratcher; I don't see "eth2" in any of the logs. One thing I noticed from code inspection that may or may not be relevant:

ACTION=="add", SUBSYSTEM=="net", KERNEL=="eth*|ath*|wlan*|ra*|sta*" \
        NAME!="?*", DRIVERS=="?*", GOTO="persistent_net_generator_do"

Shouldn't there be a comma after the KERNEL=="..." bit?

Turns out to be the logical problem, an issue with in house custom modifications to the initrd to provide persistent device naming.
