Public bug reported:
When trying to further dig into bug #575296 (no module for 2nd i2c-bus
on ASUS nForce boards), I had to realize that in Lucid's kernel the
module
i2c-core
is missing. So I cannot force to load module i2c-nforce2 at address
0x1c40 (like Hardy does automatically). This results in following error
message on boot-up Lucid:
ACPI: resource nForce2_smbus [0x1c40-0x1c7f] conflicts with ACPI region SM00
[0x1c40-0x1c45]
ACPI: If an ACPI driver is available for this device, you should use it instead
of the native driver
While Hardy correctly assignes the i2c-nforce2 to both i2c-busses:
i2c-adapter i2c-0: nForce2 SMBus adapter at 0x1c00
i2c-adapter i2c-1: nForce2 SMBus adapter at 0x1c40
In Hardy module i2c-nforce2 depends on i2c-core, not so in Lucid. Lucid
only provides i2c-core for the EC2-kernel:
apt-file search i2c-core
linux-image-2.6.32-305-ec2:
/lib/modules/2.6.32-305-ec2/kernel/drivers/i2c/i2c-core.ko
linux-image-2.6.32-306-ec2:
/lib/modules/2.6.32-306-ec2/kernel/drivers/i2c/i2c-core.ko
As a result I cannot pass any arguments to i2c-core to bind to a certain
I/O.
