Hi,

Hi,

quoted

with v3.16.0-rc1 I get the following warnings, which I did not occur
with v3.15.1:
[   14.558365] ACPI Warning: SystemIO range 0x0000000000000428-0x000000000000042f conflicts with OpRegion 0x0000000000000400-0x000000000000047f (\_SB_.PCI0.LPC_.PMIO) (20140424/utaddress-258)

How can one find out, what the native driver is, and if there is an
ACPI driver?

BTW, there is indeed one new driver that invokes
acpi_check_resource_conflict() between 3.15 and 3.16-rc1.
could you please check if CONFIG_SENSORS_NCT6683 is set in your config?
If yes, does the warning messages go away if CONFIG_SENSORS_NCT6683=n?

thanks,
rui

These are resource conflicts and I'm not sure why there were not there before.
Perhaps we introduced a new driver trying to reserve system I/O ranges
claimed by the ACPI core already.

I agree that the second part of the message is not very useful, though.

Rui and Lv (CCed) should be able to help you diagnose this problem further.
