Comment # 6 on bug 1040022 from Jiri Slaby

Hmm, the chip is found, but cannot be used AFAICS:
[   14.004770] nct6775: Found NCT6791D or compatible chip at 0x2e:0x290
[   14.004776] ACPI Warning: SystemIO range
0x0000000000000295-0x0000000000000296 conflicts with OpRegion
0x0000000000000290-0x0000000000000299 (\_GPE.HWM_) (20150930/utaddress-254)
[   14.004779] ACPI: If an ACPI driver is available for this device, you should
use it instead of the native driver

So, could you paste here the output of sensors-detect?

Also, could you pass acpi_enforce_resources=lax to the kernel to turn the above
warning into non-killer of the driver?
