Subject: it87 sensors need an ACPI driver (2.6.31)
Date: Sun, 20 Sep 2009 10:20:57 +0200	[thread overview]
Message-ID: <c43b2e150909200120kf87cdc2oabafea8abbf01227@mail.gmail.com> (raw)

Hello,
with recent upgrade to 2.6.31 I get

it87: Found IT8712F chip at 0x290, revision 7
it87: in3 is VCC (+5V)
it87: in7 is VCCH (+5V Stand-By)
ACPI: I/O resource it87 [0x295-0x296] conflicts with ACPI region IP__
[0x295-0x296]
ACPI: Device needs an ACPI driver
FATAL: Error inserting it87
(/lib/modules/2.6.31/kernel/drivers/hwmon/it87.ko): Device or resource
busy

when trying to load it87 module. On previous kernels the module worked
fine. I tried grepping for IP__ in acpi dump and found this:

OperationRegion (IP, SystemIO, 0x0295, 0x02)
Field (IP, ByteAcc, NoLock, Preserve)
{
    INDX,   8,
    DAT0,   8
}

I have also discovered that dsdt contains description of what is
connected to each it87 input. Maybe it has also some code to access
the chip? In /proc/acpi I can read only one temperature, while the
chip measures three temperatures, fan speeds and voltages. This is
desktop pc with ASUS A8N1-E maniboard, athlon64 and nforce4 chipset.

Thanks for your time.
