http://bugzilla.opensuse.org/show_bug.cgi?id=1187874 Bug ID: 1187874 Summary: Kernel hwmon modules nct6775 no longer fully recognioses chip Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.3 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: opensuse@1.opensuse.bgcomp.co.uk QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- With opensuse 15.2, the nct6775 chip was recognise and the sensor command would print details of its sensors. This no longer happens with 15.3. Running sensors-detect, the chip is not recognised, but is when the the module is loaded, although it's sensors are still not listed. The output 15.2 when the module is loaded is: 2021-03-01T19:22:02.900605+00:00 ns2 kernel: [ 7.237799] nct6775: Enabling hardware monitor logical device mappings. 2021-03-01T19:22:02.900605+00:00 ns2 kernel: [ 7.237809] nct6775: Found NCT6791D or compatible chip at 0x2e:0x290 2021-03-01T19:22:02.900605+00:00 ns2 kernel: [ 7.237814] ACPI Warning: SystemIO range 0x0000000000000295-0x0000000000000296 conflicts with OpRegion 0x0000000000000290-0x0000000000000299 (\_GPE.HWM) (20190703/utaddress-213) 2021-03-01T19:22:02.900605+00:00 ns2 kernel: [ 7.237818] ACPI: This conflict may cause random problems and system instability 2021-03-01T19:22:02.900605+00:00 ns2 kernel: [ 7.237819] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver while the output from 15.3 is: 2021-06-02T11:53:24.172296+01:00 ns2 kernel: nct6775: Enabling hardware monitor logical device mappings. 2021-06-02T11:53:24.172369+01:00 ns2 kernel: nct6775: Found NCT6791D or compatible chip at 0x2e:0x290 2021-06-02T11:53:24.172408+01:00 ns2 kernel: ACPI Warning: SystemIO range 0x0000000000000295-0x0000000000000296 conflicts with OpRegion 0x0000000000000290-0x0000000000000299 (\_GPE.HWM) (20200925/utaddress-213) 2021-06-02T11:53:24.172447+01:00 ns2 kernel: ACPI: This conflict may cause random problems and system instability 2021-06-02T11:53:24.172480+01:00 ns2 kernel: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver The only difference between the 2 outputs are with the ACPI systemIO range, but that seems to be date related, 20200925 vs 20190703.
