Random Freezes in Kubuntu 20.04

Question 1

It's my first time that I've been facing problems with Ubuntu on my machine, recently I've changed the SSD of my PC with a brand new one, it's working really well in Windows and the firmware is up to date.

Hardware

Kingston A200 NVME 500Gb (BTRS and XFS)
Hybrid Graphics(Intel HD 530, NVIDIA GeForce GTX 950M)

Software

Nvidia Driver 440 (From the Official Repositories, Prime Profile: On Demand)
Cuda Driver (From the official repository)

Sometimes, I'm using my laptop and Kwin stop working, I can't open the Application Launcher but I can change the window via the Alt + Tab key but after few seconds, the screen is completly frozen, I can't control the mouse, the temperature starts to increase, I can't switch to another console to check the error(Control + Alt + F2) and I can only restart my PC with the Magic SysRq key + REISUB.

Relevant info of my system:

Bios Version

sudo dmidecode -s bios-version
E5CN63WW

RAM and SWAP Data:

free -h
              total        used        free      shared  buff/cache   available
Mem:           15Gi       3,9Gi       7,0Gi       1,3Gi       4,5Gi        10Gi
Swap:         3,8Gi       1,8Gi       2,0Gi

Swapiness

sysctl vm.swappiness
vm.swappiness = 60

The system journal journalctl -k -b -1 (for me) didn't show anything relevant, but I'm attaching the messages with warning or alerts below, just in case I'm forgotting something

Thanks for reading. What have I done wrong? Any comment is really appreciated!

Question 2

Проблема была связана с функциями SSD, автономные переходы между состояниями питания (APST) вызывали зависания. Чтобы смягчить это, пока они не выпустят исправление, включите строку nvme_core.default_ps_max_latency_us=0 в опции GRUB_CMDLINE_LINUX_DEFAULT. Например:

GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvme_core.default_ps_max_latency_us=0"
GRUB_CMDLINE_LINUX=""

Question 3

Question 4

BIOS

Your BIOS is current at version E5CN63WW.

MDS

You have MDS and TAA errors:

aug 11 21:01:58 josejacomeb-Lenovo-ideapad-700-15ISK kernel: MDS CPU bug present and SMT on, data leak possible. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html for more details.
aug 11 21:01:58 josejacomeb-Lenovo-ideapad-700-15ISK kernel: TAA CPU bug present and SMT on, data leak possible. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/tsx_async_abort.html for more details.

Mitigation control on the kernel command line

The kernel command line allows to control the MDS mitigations at boot time with the option “mds=”. The valid arguments for this option are:

full

If the CPU is vulnerable, enable all available mitigations for the MDS vulnerability, CPU buffer clearing on exit to userspace and when entering a VM. Idle transitions are protected as well if SMT is enabled.

It does not automatically disable SMT.

full,nosmt

The same as mds=full, with SMT disabled on vulnerable CPUs. This is the complete mitigation.

off

Disables MDS mitigations completely.

sudo -H gedit /etc/default/grub

Change:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mds=full,nosmt"

Save the file and quit gedit.

sudo update-grub

reboot

Note: Understand that you'll take a HUGE performance hit on multi-cpu or multi-core configurations.

Note: If the performance hit is too great, try mds=full instead of mds=full,nosmt.

NVMe

Kingston A200 NVME 500Gb

You may have a firmware problem:

aug 11 21:01:58 josejacomeb-Lenovo-ideapad-700-15ISK kernel: nvme nvme0: missing or invalid SUBNQN field.

Go to the manufacturer's web site and check for newer firmware.

TPM

You have TPM errors:

aug 11 21:01:58 josejacomeb-Lenovo-ideapad-700-15ISK kernel: platform MSFT0101:00: failed to claim resource 1: [mem 0xfed40000-0xfed40fff]
aug 11 21:01:58 josejacomeb-Lenovo-ideapad-700-15ISK kernel: acpi MSFT0101:00: platform device creation failed: -16

Check to make sure your Software Updates are current, and that you're running the latest kernel.

Check your BIOS for a TPM setting, and disable TPM if possible.

memory

Your swap and vm.swappiness settings look fine.

Go to https://www.memtest86.com/ and download/run their free memtest to test your memory. Get at least one complete pass of all the 4/4 tests to confirm good memory. This may take many hours to complete.

Nvidia

You have Nvidia driver 440. There's a newer version available, 450.57, and it can be downloaded here.
