PCIe Inconsistency Problems

[jja2000]

Hi,

I've posted this in another thread:

I've been having trouble getting my Pine bought PCIe SATA card to work aswell.

It used to show up before but then totally disappear. The HDD spins up but does not show up in lsblk or in dmesg. There's no LED burning on the card. The HDD works aswell.

Doing a dmesg | grep pci gives me this:

Code:

rock64@rockpro64:~$ dmesg | grep pci

Okay so I installed mainline and I get a similar error:

Code:

But it happens a lot less consistently, mostly reboots and a bit of reseating of the cables makes it function again.

When it does work and I try to access the harddrive (either by mounting or by opening a partition manager via ssh) the board (presumeably, because I have no display output on Mainline and no way to read the GPIO pins for serial) kernel panics.

It kinda sucks that I can't use this device as intended. Anyone have a suggestion to make this work?
