Hi all, I am chasing a problem on a Poulsbo based board where the ACPI subsystem is blocking a chunk of memory and preventing the Poulsbo I2C driver loading. > -- > [ 403.809826] ACPI: resource (null) [io 0x0480-0x04bf] conflicts with > ACPI region PHO_ [io 0x4bc-0x4bc] > [ 403.809834] ACPI: If an ACPI driver is available for this device, you > should use it instead of the native driver > [ 403.809921] lpc_sch: probe of 0000:00:1f.0 failed with error -16 > -- If I boot with 'acpi=off' kernel option, then I2C can function as expected. As far as I can see there is no reason why ACPI should be holding onto this address block, this block is shown in '/proc/ioports' but no driver listed. The board also contains a IET IT8516 SuperIO which interfaces to the charger/batteries/etc. dmidecode and acpidump logs under the original posting: http://thread.gmane.org/gmane.linux.drivers.i2c/8154/focus=8171 Thanks in advance, Simon. -- 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
