Hi, Gergely
Sorry for the late response.
From the acpidump/lspci it seems that the SMbus I/O port(0x400-0x41f) is
used by ACPI AML code. And the I/O port of SMbus PCI device is 0x400-0x41f. The
hardware sensor driver depends the driver of i2c-i801.c. In such case if
i2c-i801 driver is still loaded, there exists the synchronous issue between
ACPI and OS kernel.
So the i2c-i801 driver had better not be loaded for the SMbus PCI device.
From the acpidump it seems that the SMBus I/O port is accessed in the ACPI
AML code related with the driver of eeepc-laptop.
Will you please double check it again? (Try the 2.6.26 kernel or disable
the eeepc-laptop driver in the 2.6.27.10 kernel).
Thanks.
