Title:
ACPI BIOS bug, Wireless NIC
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi, I'm experiencing a Wireless NIC issue. RTL8822CE can't wake up
after a suspend/hibernate, I already tried in-tree driver and
https://github.com/lwfinger/rtw88 but all of them got the same issue.
I also tried to disable `aspm` and/or `msi`, unload the kernel module
pre sleep and load it back at post sleep but the issue still presists.
It seem to be a power management issue, and later I found that there's
ACPI BIOS bug.
Env: Ubuntu 22.04, Linux 6.0.8-cfs, 5.15.0-52-generic
BIOS: FA506IH.316 (2021, and it's the latest)
Current ACPICA: 20220331:

However, previous kernel ACPICA driver version: 20201113 don't have this
issue, and it able to wake the NIC after a suspend.
Thanks!
