Hi everyone,
Here after a week. I did my research.
I talked to some folks on IRC and the glaring issue was basically this:
[ 1146.810055] pcieport 0000:00:1c.0: AER: Uncorrectable (Fatal) error message received from 0000:01:00.0
This basically means that the root port (that 1c thing written with colons) of PCIe is the main problem here.
One particular note: this issue can be reproduced on the models of this same laptop. Therefore, this happens in most if not all of the laptops of the same model.
For starters, the root port basically manages the communication between the CPU and the device. Now, this root port itself is reporting fatal errors.
This is not a Wi-Fi error, but something deeper.
Any tips on what to do?
