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
