I have just bought the Asrock B450-Pro4 (with R5 3600 cpu) and i'm struggling with ACPI.
'acpi -V' does not return anything useful:
No support for device type: power_supply
No support for device type: power_supply
Cooling 0: Processor 0 of 10
Cooling 1: Processor 0 of 10
Cooling 2: Processor 0 of 10
Cooling 3: Processor 0 of 10
Cooling 4: Processor 0 of 10
Cooling 5: Processor 0 of 10
Cooling 6: Processor 0 of 10
Cooling 7: Processor 0 of 10
Cooling 8: Processor 0 of 10
Cooling 9: Processor 0 of 10
Cooling 10: iwlwifi_1 no state information available
Cooling 11: Processor 0 of 10
Cooling 12: Processor 0 of 10
CPU temperatures (stock Stealth cooler) are also sensibly higher than those i was used with my previous system (i5-4670): with cpu governor set to ondemand (boost enabled), the idleT is 65°C and suddenly rises to 91°C when 'stress -c 12' is run.
Dunno if this has to do with lacking of ACPI data...
Do you have any recommendations on how to get ACPI working properly?
I am a little clueless with the B450. I have the Asrock B550M Pro with the R5 3600 proc and have had no problems with it.
I did not use the cooler provided by AMD with that proc but installed an AIO water cooler Corsair H115i with 280mm radiator.
At idle it runs ~45C and at 90 to 95% load it runs ~70C. I suspect that with the cooler AMD provided the temps would be a lot higher.
EDIT:
I just ran stress on it and the temp never exceeded 71C.
Personally I would suspect that the temp is related to the inadequate cooler for high loads instead of ACPI.

indeed i think these may be unrelated issues... in order to lower cpu temps, I have just ordered a beefier aftermarket cooler. It should bring temp down by 20°C (at least according to marketing specs). Will update on this later.
Regarding ACPI, i don't have any clue why it is actually broken in my system. I cannot figure out if it's a MB or software issue.
AFAIK the system cannot do power saving tasks without ACPI. Still, interestingly the system hibernates/resumes properly.
Hope some user with similar specs will share his output here.

I just installed acpi and get the same as you, no data except the battery status on my keyboard and mouse and cooling on all processors but no temps. It says it is a monitoring program so maybe it does not do what you think it does.
This from the man page.
Code:
DESCRIPTION
acpi Shows information from the /proc or the /sys filesystem, such as battery status or thermal information.
I have lm-sensors installed with gkrellm and it monitors stuff for me with a nice screen display

Regarding your question, we searched on the internet and it seems that need to wait for the latest Linux kernel to support AM4 ACPI.
Please note: B450 Pro4 only supports Windows 10 64-bit.
sounds odd to me, but that's it.
maybe i'm just lucky that it boots...

Asrock only officially supports windows so their canned answer is "not my fault". In other words they will never give you support of any kind, or at best generic suggestion that they guess at to avoid potential liability. However, most of their boards have done well with linux and many use them, myself included.
I agree with you.
What sounds odd to me is the need to wait for the latest Linux kernel: this MB has been around for a while...
... but if Asrock support is right, that would be great!
See your other thread for my system data. I don't think you have a system problem, just need better cooling and maybe a change in bios settings for the fans.
BTW, I am using fedora 33 with the 5.11.7 kernel right now.
