turned out the problem was some weirdness between minicom/memtest on serial. I resized the terminal window that minicom was in and memtest has been running fine for almost 5 hours.
I also have mode cache enable around so that it happens in disable_car. This helps a bit. But I still feel we're not caching ROM. ron -- coreboot mailing list coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
