Well, looks like I'll have to bisect to hunt the problem down. Obviously there is something with transparent hugepages that the R10K-family dislikes. Just a question of "what?". Seems like I'm the only one left with this kind of equipment and interest to play with it :) -- Joshua Kinard Gentoo/MIPS kumba@xxxxxxxxxx 4096R/D25D95E3 2011-03-28 "The past tempts us, the present confuses us, the future frightens us.
