I installed Debian 11 on my t440p Lenovo. It was a fresh install. Everything works fine, except I cannot Shut Down the laptop and cannot wake the laptop from suspend. No matter how I attempt to shutdown the machine, it freezes after running the shutdown commands [screenshot: https://pasteboard.co/vnp7siYRM2Zf.jpg]. Shortly after it freezes, the cpu fan gets really loud. The machine will only shutdown after holding the power button for 10 seconds.

I was able to narrow down which PCI id causes the system freeze by running lspci -s <pci-id>. Pasted below is the trouble id. All other PCI ids work fine.

edit 1:
Noticed this ACPI error message when booting [screenshot: https://pasteboard.co/tgBmuiiw6Zgs.jpg]. Might be helpful in debugging.
