And one of the reporters there has done a git bisect and has found the commit which is causing the problem for them:
"""
git-bisect points to 719e1f561afbe020ed175825a9bd25ed62ed1697 :
"ACPI: Execute platform _OSC also with query bit clear".
Tested 5.12.9 kernel with the commit reverted, and confirmed that the error
messages are gone. (I had to revert
5a6a2c0f0f43676df27632d657a3f18b151a7ef8 for dependency too.)
It also brings back the /sys/devices/system/cpu/cpu0/acpi_cppc which is absent
in the stable 5.12.x
Hope this helps

Can some one seeing the "Could not resolve symbol [\_PR.CPU0._CPC]" error try building a 5.12 kernel with the 719e1f561afbe020ed175825a9bd25ed62ed1697 commit reverted and see of that helps please?
