APST

2023-01-28 - Saturday - 01:35 PM - My Laptop Log.

My 2023 ASUS Laptop froze again. It froze yesterday too. It freezes too often. See log for more info.

To mitigate it, until they will release the fix, include the line nvme_core.default_ps_max_latency_us=0 in the GRUB_CMDLINE_LINUX_DEFAULT options." heynnema wrote: "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. You have Nvidia driver 440. There's a newer version available, 450.57, and it can be downloaded here."

Disable APST?

I edited a grub file via Terminal, changes as follows. Changing latency to zero might disable APST which is a power saving mode for SSD drives or whatever.
sudo nano /etc/default/grub

---

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

I changed the preceding to the following:
GRUB_DEFAULT=10
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
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"

ADATA Swordfish 1TB 3D NAND PCIe Gen3x4 NVMe M.2 2280 Read/Write up to 1800/1200MB/s Internal SSD (ASWORDFISH-1T-C). Amazon.
Interface:M.2 2280 PCIe Gen3x4 NVMe 1.3. This has Dram someone said.
Read/Write speed up to 1800/1200MB/s Performance varied by drive capacity and system configuration
Fast performance with SLC Caching and host memory buffer
Random 4K read/write of 180/180K IOPS Varies by models
Ultra-fast PCIe Gen3x4 interface
R/W speed up to 1800/1200MB/s
NVMe 1.3 support
Advanced hardware LDPC ECC Technology
Supports SLC Caching for improved performance
AES 256-bit encryption support
Support Host Memory Buffer(HMB)
3D NAND Flash for higher capacity and durability
Compact M.2 2280 form factor – ideal for video editing, industrial drawing, programming
SSD Toolbox and Migration Utility Included
PCIe Gen3x4 interface and complies with the NVMe 1.3 standard
Sustained read/write speeds of up to 1800/1200MB/s
M.2 2280 specification: Supports the next-generation platforms of Intel and AMD. Suitable for both desktop and notebook
With support for LDPC (Low-Density Parity-Check) error correcting code technology, the SWORDFISH can detect and fix errors to ensure data integrity and thus enjoy an extended lifespan. AES 256-bit encryption keeps the data inside password-protected and away from prying eyes.
The Falcon uses Micron memory and the Swordfish SanDisk memory. The Falcon has higher rating Endurance (TBW). Someone wrote: "I have the 2tb versions of both the FALCON and the SWORDFISH. Both have TLC flash memory, which is almost always better than QLC." Somebody wrote: "Looking around at reviews for similar SSDs (e.g. HP FX900, XPG Atom 50) with the same controller and flash combo (InnoGrit IG5220 + Micron B47R), I found a few other people mention the same symptoms. Ultimately it seems like there's some sort of incompatibility between my laptop and the controller firmware."

These are instructions passed to the kernel during the boot time. In Ubuntu, they are managed by the GNU GRUB (GRand Unified Bootloader).
Quiet - this option tells the kernel to NOT produce any output (a.k.a. Non verbose mode). If you boot without this option, you'll see lots of kernel messages such as drivers/modules activations, filesystem checks and errors. Not having the quiet parameter may be useful when you need to find an error.
Splash - this option is used to start an eye-candy "loading" screen while all the core parts of the system are loaded in the background. If you disable it and have quiet enable you'll get a blank screen.
Nomodeset - tells the kernel to not start video drivers until the system is up and running.

Option:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
