This would not change acpidump output, just the kernel. Are you able to capture the boot messages with this kernel? Specifically, do you get any error messages from ACPI? Also, what happens if you find the code that uses ACPI_CHECKSUM_ABORT (I think in sys/contrib/acpica/tables/tbutils.c) and put #if 0 around that block? -- John Baldwin
