Hi,

I have some problems to provide logs. If I add -DDEBUG to cpuidle44xx.o 
the problem doesn't seem to occur. It could be that printk-ing 
alleviates the issue.

Also the watchdog seems to shutdown the device rather than rebooting it 
(or it hangs?) and then I can't provide /proc/last_kmsg.

How could I provide more info?

Rgds,
Chris
