I had last week a catastrophy: motherboard or processor dead (no other motherboard nore other AMD FX to diagnose).
In the urgency I changed the whole set: motherboard and processor.
I kept the RX550 and that’s all.
At boot, Linux seems to work but no ip address, no network, and no KDE.
I got lot of ACPI error messages at boot.
Linux works in runlevel 3 without any problem but I would like to run KDE again ^^
I use the amdgpu-pro proprietary driver for the RX550.
Looking at the logs Xorg.0.log the last message is “no screen found”.
The network issue can’t be resolved, I don’t know why this is a realtek but I don’t know the chipset (lspci gives RTL8111 but this is the driver choosen, I will look at BIOS in the B550 asrock it is rtl8111h)
I need help here for different reasons:
I read in different articles that some BIOS may be updated in order to be fully supported by the kernel -> I’m using a Ryzen 7 processor.
Do you confirm that Ryzen 7 could be supported by this kernel ? (4.12.14)
I need steps in order to set KDE back.
Concerning the dual boot with windows 7, this one is completly dead, it reboots at windows boot even in “secure mode”.
Do you think it is better to backup linux system personnal settings then reinstall windows 7, then reinstall linux as new ?
Or there is a way to prevent windows 7 to “loop in boot” ^^ (I think the reinstall as new would be better but i’m not sure)
I have a Ryzen CPU and a B550 motherboard (MSI Tomahawk). And the same GPU - RX550.
Here everything is working fine with TW and kernel 5.8.7 (also another PC with MSI B450 Tomahawk MAX is fine).
I have the same ethernet chipset (RTL8111h).
There are some error messages
