Hello, I'm writing here because I am a bit desperate and figured it's worth a shot. I have a Lenovo E480 with Radeon RX550 https://www.lenovo.com/in/en/laptops/thinkpad/thinkpad-e-series/ThinkPad-E480/p/22TP2TEE480 . The computer shuts down when I do lspci, hwinfo, or start lutris (for games) and sometimes when I log-in after resume. Otherwise the computer works great and there are no issues. If I disable acpi during kernel boot --acpi=off lspci works ok. Any idea what is happening? Any idea how I can disable ACPI scanning for the GPU / new video devices ?! Any ideas on what to try to fix this? More information: * Running Debian 11.3 Linux 5.10.0-15-amd64 #1 SMP Debian 5.10.120-1 (2022-06-09) x86_64 GNU/Linux * I took the laptop to two repair shops. thermal paste was replaced. * I upgraded Bios to latest version. One thing that I did notice is that I can't see the dedicated Radeon GPU in lspci. Ouptut from lspci, lsmod and dmesg: lspci -nnk -> https://paste.debian.net/plain/1246205 lspci -> https://paste.debian.net/plain/1246206 lspci -vvv https://paste.debian.net/plain/1246207 lsmod -> https://paste.debian.net/plain/1246207 dmesg -T https://paste.debian.net/1246209/ Thanks, Eugen
