Hello, My Linux (v.2.4.22) running on a PowerPC 750 system does not seem to know the memory bound when ramdisk is installed. The system has 128 M memory and 28 Meg of the memory is used as ramdisk. I setup the memory size as 128M bytes at the kernel parameter and ppc_md.find_end_of_memory() routine returns constant 128M.
The kernel dies with " Oops: kernel access of bad area, sig: 11". The area it accessed is the start of the last 28 Megabytes of the 128 M memory. It happens when the kernel tries to allocate memory for socket communication. How can I know the kernel knows the end of memory correctly? Could it be other problem?
