Lenovo Legion 5 15ACH6H (AMD, 82JU, 2021) random reboots.

The laptop itself reboots (the screen just goes black and the machine starts to boot up). This happens frequently. I didn't see anything suspicious in the logs, and there are no records of the cause at the moment of the shut down. I found a workaround that significantly reduces the number of these sudden reboots: running something three-dimensional (like the spinning cube with goverlay constantly minimized).

There are no problems when running on battery power.

What I have tried:
1. Using the lts kernel.
2. Switching to discrete graphics in UEFI mode.
3. Disabling C6-state in kernel parameters.
4. Different versions of the Nvidia driver.
5. Reinstalling the system.
6. Xorg \ Wayland.
7. Different versions of amd-ucode.
8. Completely disabling BT \ Wifi modules.
9. Disabling swap.

One of the recent updates has added new symptoms - now the laptop must always be in red mode (performance can be switched using Fn+Q) or the workaround stops working completely. Also, connecting via Bluetooth (to a headset, for example) increases the number of reboots.

The hardware is 100% functional, and there are no similar issues on Windows.

Where should I start looking, and what data should I provide for diagnosis?

This also happens to be, and I'm using ThinkPad P15V with intel CPU and I meet exactly the same problem as you since an update in May and I cannot figure out why. I got a lot of strange messages in system journal like:

before reboot. I dot know if you have similar problems.

Edit:
It seems there exist some bugs in nvidia driver, when I totally disabled nvidia drivers and devices, everything just works fine.

Re: Lenovo Legion 5 15ACH6H (AMD, 82JU, 2021) random reboots.

I have a Lenovo IdeaPad gaming 3. They have the same mobo 15ach6h with rtx 3060.

Have you updated your uefi firmware?
Are you enabling the nvidia-resume suspend etc?

And lastly: have you configured this?

`/etc/modprobe.d/nvidia.conf`:

options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp NVreg_UsePageAttributeTable=1

And you should also enable Early kms.

The last option would be disabling the GSP firmware and see if the problem persists.

Re: Lenovo Legion 5 15ACH6H (AMD, 82JU, 2021) random reboots.

Hey all, same issue. just started today which was really off putting. is this an issue with just the newest nvidia driver? I had left my laptop without an update and the reboots had started on that approx 2 week old version.

Re: Lenovo Legion 5 15ACH6H (AMD, 82JU, 2021) random reboots.

I have also started experiencing random reboots on my Legion 5 15ACH6H. I had been having issues with it freezing but that seemed to get fixed after a BIOS update.

There is nothing suspicious in the logs leading up to the random reboots and I haven't had much luck with getting extra information using netconsole logging or using the crashkernel functionality with kexec. Although those not working may just me not correctly setting them up. I have also done a memtest with no issues reported by it.

The most reboots I've gotten is when i have a YouTube video playing. It's completely stable under load.
