MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi: I have linux 2.4.30 runnning on this board, the "reboot -f" command cause machine check and kernel ooops. The problem seems in the "m8260_gorom" in head.S. The restart() function in m8260_setup.c passed 2 parameters to that assembly code, r3 is the bd_info , r4 is the warm start address, I changed it to 0xFF800100, that's where the u-boot's _start_warm lives, I have verified that address by typing "g ff800100" in u-boot console, which cause the board reset. I assume the m8260_gorom has been heavily tested for other boards. I wonder if anyone got a PQ2FADS-VR board that has the similar problem? I am not familar with the assembly code for PPC. Any suggestions? Thanks lei
