Sata HD stopped booting

[db579]

I have a RockPro64 running Ubuntu 4.4.190-1233-rockchip-ayufan-gd3f1be0ed310. It boots from emmc and has a hard disk attached via SATA.

After working fine for a long time, since last week the hard disk doesn't seem to be recognized. It doesn't show up in `fdisk -l` for example and isn't mounted anymore.

If I plug it into another laptop the drive mounts and is visible so I don't think it's dead. dmesg contains `PCIe link training gen 1 timeout!` which may be related and the last time it successfully mounted the linux-firmware package was updated via apt from 1.187.25 to 1.187.26. The older version no longer seems to be available to rollback to so unsure if related.

Anybody seen this before or know what to do here?

Not sure how familiar you are with Linux but a bit of googling should yield some answers. In the meantime have a read up on this https://www.maketecheasier.com/downgrade-kernel-linux/

@Rocklobster  thanks very much for the hint. I'd completely missed that there was a kernel upgrade in there as well. Downgrading was slightly different than in your link since it's u-boot rather than grub I commented the running kernel out of `/boot/extlinux/extlinux.conf` and rebooted and the drive is mounted again fine.

So it seems `4.4.167-1213-rockchip-ayufan-g34ae07687fce` works fine but ` 4.4.190-1233-rockchip-ayufan-gd3f1be0ed310` does not.
