| |
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
