SubjectMAC firmware does not load due to (commit 288d5abe usermodehelper)
I have some ARM IXP4xx based machines that use the two on chip MAC
ports (aka NPEs). The NPE needs a firmware in order to function. Ever
since the following commit, it is no longer possible to bring up the
interfaces during the init scripts.

commit 288d5abec8314ae50fe6692f324b0444acae8486
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date: Wed Aug 3 22:03:29 2011 -1000

Boot up with usermodehelper disabled

A warning appears on the console, shown below. I don't know what
commit 288d5abe was trying to fix, but it sure made a regression for
me. It probably would also spoil using NFS boot, too.

Any ideas what to do about this?

Thanks,
Richard
