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.
