The acpi_ipmi failure happens because my ipmi_si device is being probed through SMBIOS, not ACPI. I do have /sys/bus/acpi/devices/IPI0001:00, which has physical_node /sys/devices/pnp0/00:05 and firmware node /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:15/IPI0001:00. My DSDT has: Device (NIPM) { Name (_HID, EisaId ("IPI0001")) // _HID: Hardware ID Name (_CID, EisaId ("PNP0C01")) // _CID: Compatible ID Name (_UID, 0x05) // _UID: Unique ID so I assume it should be probing via ACPI. I haven't figured out why it's probing via SMBIOS instead yet. --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
