Ok many thanks for the tips.
Refering to the webpage, actually the cause should be :
* If the kernel locks at "Calibrating delay loop...", it means
that the timer interrupt is not ticking and that the delay calibration
routine is running an infinite loop at while (ticks == jiffies) in
function calibrate_delay, file init/calibrate.c. To help debugging
this situation, you can put printks in the while (ticks == jiffies)
loop, printing any hardware timer registers or status register you want.
It seems that S3C2440 / Mini2440 Timer has changed. There is no more
register named S3C2410_T...
But I have no experience in debugging ARM cpu hardware timer... Nor
have time to investigate further how to debug the port...
You can still find the kernel on FriendlyARM.net
