The boot succeeds (and appears to bring initialize the network adapter 
properly - it autonegotiates a 100Mbps link speed), but the dhcp client is 
never able to get an address.  However, applying the rc2-mm1 patch series up 
to just before:

  add-64-bit-capability-support-to-the-kernel.patch

results in a working kernel.  Applying just this patch causes the failure.  To 
be sure, I also tried applying the above patch plus the following ones:

  add-64-bit-capability-support-to-the-kernel-checkpatch-fixes.patch
  add-64-bit-capability-support-to-the-kernel-fix.patch
  add-64-bit-capability-support-to-the-kernel-fix-fix.patch
  remove-unnecessary-include-from-include-linux-capabilityh.patch

but the problem still occurs even with all of these.

As to versions, I'm running Kubuntu gutsy, so I have the default:

dhcp3-client           3.0.5-3ubuntu4
libcap1                1:1.10-14build1

packages installed.

Let me know if you need any other information, or if you have a patch you 
would like tested.
