System crashes due to SSD

Hello everyone!
Recently I've bought Kingston A2000 (1TB) and did a fresh install of Manjaro KDE. At first, everything was fine but after a while, my system starts to freeze without any reason. First I thought that it was KDE (there are still some warnings in KSystemLog about kwin_x11, krunner, and plasmashell) but I wasn't able to switch to tty, and during one of these crashes I've found this
By searching the internet I've found that there were some kernel bugs:
But I don't know is this bug fixed already or not.
I was trying several different kernels (linux-pf, linux-xanmod, and stock Manjaro-5.7.9-1) but there are still these crashes.
Also, I was trying nvme_core.default_ps_max_latency_us=0 and nvme_core.default_ps_max_latency_us=5500 but my OS still crashes from time to time.
And here's my inxi -Fxxxza --no-host

SMART overall-health self-assessment test result: PASSED

I can provide any other info that would help to fix this. Thank you!

did you try to update kernel to 5.7.9?

You mean custom 5.7.9? I can't update none of my custom kernels because my system hangs during compiling it.

You could try switching to unstable branch and run a full update.

sudo pacman -aS unstable -u && sudo pacman -Syyu

This will bring you on 5.7.10.

My systems is Intel based so I can't be of much help otherwise. I have heard of this 'bug' with nvme devices but - luckily - I have never been affected by it.

I think this wouldn't help me. When I'm installing something small from AUR or Official Repos (doens't matter) everything goes fine, but when I'm trying to install(and compile) something bigger like custom kernel - my system just hang about to 3/4 of process.

It sounds like it is a memory / cache issue? The /tmp dir runs full? Try changing the /tmp mount from tmpfs to physical?

I think it doesn't connect to this, because system can hang when I'm turning my laptop off or rebooting it. Also it may hang during gaming or even just after login into system. But I'll give a try with your advise.

You are probably right - just worth mentioning :slight_smile: - I understand why you are puzzled - I am too because I have never experienced an issue like it - just read on it briefly some time ago.

Dumb question, have you tried doing the kernel update via a TTY? I had a similar issue with my Western Digital NVME drive and that is how I had to do a kernel update (4.19). I still have to use the kernel argument you mentioned above.

Nope, but I'll give it a try! Is that kernel argument helped you?

Yes it did. I use the nvme_core.default_ps_max_latency_us=5500 argument. You should be able to drop to a TTY right at the login screen by hitting ctrl+alt+F3. If a new kernel doesn't work, try uninstalling TLP. It may be putting the drive into a "standby or sleep" state.

I am on my phone so I hope the formatting is correct. I had to do the above process over a year ago. Currently I am running the latest Linux-Zen kernel and I am not having any issues.

BTW, my laptop is an Asus FX504G.

I need to uninstall TLP or replace it with something else ? I'm already turned off all sleep/hibernate options in system power management.
So you say that you don't have issues like mine with same/almost same hardware?

My laptop is a generation behind yours using an Intel processor. I had some major problems when I first got it over a year ago, but they have all been resolved now.

I would just uninstall TLP and not replace it with another program. If that doesn't work, you can always reinstall it.

Also, make sure that you are using the latest bios. You can get to it by holding down the Esc key when you first power on your laptop. This will bring up a "boot" menu. Choose "setup". Asus has a real nice utility that allows you to update the bios while in the bios. Just make sure to disable secure boot again after updating.

If memory serves, those settings do not affect TLP. TLP has to be configured separately. Either by the terminal or using the program TLPUI.

Like I said, I hope I am remembering correctly.

Sorry about the double post.

Checked BIOS version - I have 315(last version on of. website).
Checked etc/default/grub - there was nvme_core.default_ps_max_latency_us="5500" , I've deleted quotes and tried again with and without TLP (within tty and under graphic session) - system still hangs during compiling something huge. Are there any special packages for SSD?
Besides, I have zram and zswap packages installed so I can't run out of RAM or something like that.
I don't want to switch to another distro (maybe a pure Arch if it will fix this) but this problem ruins my work and game processes.

In pamac - cache is 0 and there are only 1.5GB of AUR files in tmp directory.
