Hi Paul,
I think I have seen your previous log that get_top_of_mem() was missing. maybe someone broke it some time ago. I did not try with this board since I have the new fm2 board.
The get_top_of_ram() is in early_car.c in southbridge/via/k8t890
It has still CONFIG_HAVE_ACPI_RESUME I seen some efforts of removing this... Not sure what is the state now.
Please check if you dont see the messages WARNING: you need to define get_top_of_ram()
The top of ram mechanism is quite simple. Since this chipset has integrated VGA it is not possible to just read TOP or TOM2 MSR. Instead during the initialization a top of ram is written via backup_top_of_ram() to the NVRAM at offset K8T890_NVRAM_TOP_OF_RAM.
You could also check if you are not hitting some errata of the CPU or if CBMEM console does not interfere.
Thanks
Rudolf
