Hello dear forum user, I came in a great need.
I use ubuntu for almost 10 years for now, until now I always was able to fix, if a problem occured, but this really stopped me now.
Long story short, i bought a new Acer a315-23-A8DS for my Mum, she uses ubuntu on her current system, so I wanted to make it the same for her.
ryzen athlon 3020e. + wd sn520 120gb nvme ssd.
Windows worsk fine on the machine, so I am preatty sure the machine has no porblem.
To recap:
- ssd in ahci mode (bios won't even gives option to change it)
- secure boot off
- fastboot off
- uefi fresly updated to the latest
- nvme ssd firmware already up to date
- tried installers: 20.04 , 20,10 also mint 20.04
The Ubuntu install media boots sucsesfully, but can't find the nvme ssd.
dmesg gives the following error
The complete dmesg: https://pastebin.com/fNgAjv2d
From this I think the problem is somwhere in the communication or power states.
I found similar problems on the net, most notably on the wd forum.

I tried to add in grub nvme_core.default_ps_max_latency_us=5500, I also tried with 5000, 5200, 14000 latency.
But the problem still remained.
I also tried to add acpi=off, with this the install media freezed out on boot, I didn't got into the lvie-cd.
Furthermore: I have my own nvme ssd in my rig,so i swaped it from my pc to test it like that.
with the nvme ssd from the acer in my desktop, the install media: both ubuntu install media freeze out while loading in. mint istall starts, but fails while formating the drive.
With my desktop ssd in the acer, all install media freeze out.
I have an ubuntu on that drive with luks, it loads until it get's to the lusk password, but when I enter it, can't find the lvm group for it.
This part where I can't install onto a different drive, bugs me the most.
I am not 100% sure if the problem is the drive itself, or some controller on the board.
It has a place for a sata drive, butl lacs the sata zif cable and the cage. My plan B is to order a cable from e-bay and try it with a sata drive, but at this point I am not sure that would work, also it would take like 2 months to arrive from china, and I wanted to give it to my Mom as a christmas present. (guess i will have to give her windows)
Pardon me, if I am not clear, this is my first post here.
