The cpu is not online anymore and top does not list it. I can be re-enabled. Everything looks ok, except that error message. It worked fine in 2.6.33. I don't know if it's a ppc specific bug. $ uname -a Linux Jay 2.6.35.4 #3 SMP Sat Sep 18 20:03:06 CEST 2010 ppc 7455, altivec supported PowerMac3,6 GNU/Linux -- Giuliano.
