This warning is quite common. Do you have any issues? https://www.google.com/search?q=%22hpet_acpi_add:+no+address+or+irqs+in+_CRS%22&tbs=qdr:y&sa=X
I have only used the device again for some days, so no idea, if there are user facing issues. $ cat /sys/devices/system/clocksource/clocksource0/available_clocksource tsc acpi_pm $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource tsc If it’s not going to cause issues, then the log level should be reduced, and maybe also more background on the effects given to the user.
This warning is also logged on the Dell Precision 3540 with the latest firmware 1.23.0: [ 0.819881] hpet_acpi_add: no address or irqs in _CRS
It seems to be a more general problem. Linux warns about this also on a Supermicro Super Server/X13SAE. ``` $ dmesg | grep -e "Linux version" -e DMI: [ 0.000000] Linux version 5.15.94.mx64.447 (root@theinternet.molgen.mpg.de) (gcc (GCC) 10.4.0, GNU ld (GNU Binutils) 2.37) #1 SMP Sun Feb 19 18:42:34 CET 2023 [ 0.000000] DMI: Supermicro Super Server/X13SAE, BIOS 2.0 10/17/2022 $ dmesg --level=warn [ 2.051956] ENERGY_PERF_BIAS: Set to 'normal', was 'performance' [ 3.769316] pnp 00:04: disabling [mem 0xc0000000-0xcfffffff] because it overlaps 0000:00:02.0 BAR 9 [mem 0x00000000-0xdfffffff 64bit pref] [ 5.074722] hpet_acpi_add: no address or irqs in _CRS [ 5.824016] acpi PNP0C14:01: duplicate WMI GUID 05901221-D566-11D1-B2F0-00A0C9062910 (first instance was on PNP0C14:00) ```
