I experienced multiple crashes and oopsen, which I quickly discovered were the result of bringing at least one CPU back online. echo 0 >> /sys/devices/system/cpu/cpu1/online Works, but then if I try to do: echo 1 >> /sys/devices/system/cpu/cpu1/online I get an oops. Unfortunately this board has no serial ports so I've taken a digital camera shot of the oops. From dmesg, I'm using the PM timer. [alistair] 02:13 [~] dmesg | egrep time\.c time.c: Using 3.579545 MHz PM timer. time.c: Detected 2500.768 MHz processor. time.c: Using PM based timekeeping. http://devzero.co.uk/~alistair/oops-20060213/ Find the oops, my config and dmesg for a successful boot at this location. -- Cheers, Alistair.
