The machine passed the memory test while on battery fine. however, while on battery the checksum failed with i/o errors, it did complete the checksum normally while on AC. I think my next step will be to try and disable acpi, and to try and reproduce the error again. i suppose it could be an issue with a flakey controller, but I havent seen any related issues while I was running windows or ubuntu on the machine. if it isn't an issue with power management, I guess I'll learn some kernel debugging.
