linux box getting hanged
i have a unit having linux os working under some proprietary software.
the problem with this box is iget this error after lilo booting
"Warning Unknown PCI Device(104C:AC21).
please read include\linux\pci.h
now what happens is that sometimes the booting process goes ahead of this warning and the box functions properly for about 2 hrs. and then the box gets hanged with no response whatsoever.
and sometime it does not go ahead of this warning.
the box is used as an dhcp server.
having 2 lan cards one external and one is in the m,otherboard.
