<BR>* Environment
<BR>board : IBM Walnut(IBM PowerPC 405GP Rev. D)
<BR>bootloader : u-boot 0.4.0
<BR>linux kernel : Montavista Linux Preview Kit 3.0 modification -> mkimage
<BR>
<BR>
<BR>"Real time clock seems stuck!" messeage comes out but
<BR>real stuck position is on sti() in _start_kernel() (init/main.c)
<BR>
<BR>I tested in OpenBIOS bootloader using same kernel source and
<BR>it worked fine...
<BR>
<BR>what do i do for u-boot and kernel setting ??
<BR>
<BR>please, help me. refer to following rom monitor messeage for checking...
