kernel hangs after printing "Calibrating delay loop ..." on mpc860

[Joakim Tjernlund]

Hi List

Every now and then my kernel gets stuck after printing "Calibrating delay loop ..."
and I have to press the reset button to recover.

Someone else has experienced this on a 8260 board. This board did not have a RTC
and the fix was to add a set_tb(0,0) early in arch/ppc/kernel/time.c/time_init

Our board has a RTC but it gets initialized very late(after the Calibrating
delay loop stuff).

Either one of us can't understand why this would fix the problem and since I can't
repeat the problem at will I can't verify if a set_tb(0,0) will fix anything.

Can anybody explain why(or why not) a set_tb(0,0) will make a difference?
Kernel is linuxppc_dev, 2.4.20
