System: NetBSD gorilla.13thmonkey.org 9.99.94 NetBSD 9.99.94 (GENERIC) #7: Fri Mar 18 15:24:47 CET 2022 reinoud%gorilla.13thmonkey.org@localhost:/tmp/obj-udf/sys/arch/amd64/compile/GENERIC amd64
Architecture: x86_64
Machine: amd64
>Description:

When trying to suspend/sleep my machine with an AMD CPU its prevented by the
missing power support :
[   337.910356] acpi0: entering state S4
[   337.910356] Devices without power management support: amdsmn0 amdccp0
[   337.910356] acpi0: autoconfiguration error: aborting suspend

Detected by autoconf:
[     1.048885] amdsmn0 at pci0 dev 0 function 0: AMD System Management Network
[     1.048885] amdzentemp0 at amdsmn0: AMD CPU Temperature Sensors (Family17h)
[     1.048885] amdccp0 at pci11 dev 0 function 1: AMD Cryptographic Coprocessor

	
>How-To-Repeat:
Try to suspend/sleep the machine with 
sysctl -w hw.acpi.sleep.state=4

	
>Fix:
Implement possibly trivial power management hooks
