CPU 1 refused to die! (pmac dual G4 MDD)

[Giuliano Pochini]

When I do:

echo 0 >/sys/devices/system/cpu/cpu1/online

it waits for a few seconds and dmesg reports:

CPU1 offline
CPU 1 refused to die!

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.
