You can try hacking src/usr.sbin/acpi/acpidump/acpi.c to disable the checksum check for the XSDT. Just look for the 'XSDT is corrupted' string in that source file and comment out the call to acpi_checksum(). Something like this: rsdp = (ACPI_TABLE_HEADER *)acpi_map_sdt(rp->XsdtPhysicalAddress); if (memcmp(rsdp->Signature, "XSDT", 4) != 0 /* || acpi_checksum(rsdp, rsdp->Length) != 0 */) errx(1, "XSDT is corrupted"); addr_size = sizeof(uint64_t); Then see if acpidump -d -t gets any further. I would also look for a BIOS update perhaps, and/or complain to your motherboard vendor that their BIOS is broken. -- John Baldwin
