[Bug 575296] Re: Ubuntu boot delay - nForce error

[ingo]

Here the chipset information as obtained with Lucid  (MoBo: ASUS M2N-E)
by:

 # lspci -v | grep -A9 SMB

00:01.1 SMBus: nVidia Corporation MCP55 SMBus (rev a2)
	Subsystem: ASUSTeK Computer Inc. Device 8239
	Flags: 66MHz, fast devsel, IRQ 10
	I/O ports at fc00 [size=64]
	I/O ports at 1c00 [size=64]
	I/O ports at 1c40 [size=64]
	Capabilities: [44] Power Management version 2
	Kernel driver in use: nForce2_smbus
	Kernel modules: i2c-nforce2

So, at least the 3rd bus with I/O at 0x1c40 is not served by the module
due to above ACPI-conflict:

i2c i2c-0: nForce2 SMBus adapter at 0x1c00
ACPI: resource nForce2_smbus [io 0x1c40-0x1c7f] conflicts with ACPI region SM00 [io 0x1c40-0x1c45 64bit pref disabled]
ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
nForce2_smbus 0000:00:01.1: Error probing SMB2.


Is there a possibility to force module 'i2c-nforce2' to bind to 0x1c40?
