Subject: Oops MPC8343 @ 2.6.25-rc7

All,

I'm having trouble booting a MPC8343 into a recent 2.6.25-rc7 kernel.

Kernel config has been reduced to a minimum : no PCI, no netwoking, i2c, 
spi ...
dts has been reduced to the CPU, soc and ipic nodes.

U-Boot fills out dtb correctly - as far as I can see.

Kernel crashes on various "of_" functions regarding to call trace.

There's also strange messages :
WARNING: Estimating decrementer frequency (not found)
WARNING: Estimating processor frequency (not found)

They're coming from "generic_calibrate_decr()" in kernel/time.c.

Looks like there something basically wrong with my dtb 
location/processing, since the "timebase-frequency" is present and valid :

        cpus {
                #address-cells = <0x00000001>;
                #size-cells = <0x00000000>;
                PowerPC,8343@0 {
                        device_type = "cpu";
                        reg = <0x00000000>;
                        d-cache-line-size = <0x00000020>;
                        i-cache-line-size = <0x00000020>;
                        d-cache-size = <0x00008000>;
                        i-cache-size = <0x00008000>;
                        timebase-frequency = <0x03f940aa>;
                        bus-frequency = <0x0fe502a8>;
                        clock-frequency = <0x17d783fc>;
                };
        };

Any hints ?
