Recent netinstall.lif images fail to boot on a B180L

Hi all,

I tried netbooting using the netinstall.lif images built recently (builds
200603050000Z, 200603090000Z, 200603110000Z), and all cause a kernel panic, which
is as follows (I'm not using a serial console, so I retyped this, sorry if I made a typo):

Not sure that's too useful for anyone, but thought I'd include it.  I'm running
a B180L.  I was successful at netbooting an older version of the netinstall.lif
file from a build back in August (unfortunately I no longer have that file).

Regards,
