We are bringing up an 8540-based board, and are getting hangs at random spots when booting Linux. Sometimes the hangs occur while the kernel is initializing, sometimes the boot gets far enough where I can log in and run a couple of programs. Eventually the board locks up with no oopses or panics. If I connect to the board with a debugger, the processor is usually stopped in the Data miss exception handler, and there is usually memory corruption in the kernel code.
I ran memory tests using both Edink and U-boot and they all passed, so I'm reluctant to blame hardware for the memory corruption. Has anyone seen similar behavior, or have any suggestions of things I might try? Thanks in advance Aaron Cordes ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
