Is anyone else having zstd decompression/checksum issues?
Hello,
I recently wiped and reinstalled Arch by hand; and starting from the install process (pacstrap'd, partioned by hand due to mdadm and lvm) I've been having zstd decompression issues via checksum mismatches during decompression on kernel modules for initramfs and as well as at install with pacman, making install and now configuration of the system a pain to say the least.
The issues with package installs is usually a random files such as:

And I was wondering if anyone else is seeing these as well? The system is fresh, so as I'm concerned is up to date (installed less than 24hrs ago). I have a slew of strace's I took during attempted installation last night if anyone is interested.
Mods: if this is in the wrong subforum please excuse me and relocate if needed.
Thanks in advance

The issues with package installs is usually a random files such as:...
What is all that from?? You're showing checksums of files under your home directory - packages do not contain anything under /home/.
Post the actual commands and complete output that are problematic.

Those are the files that failed their checksum during install. I had removed them and moved them to my /home partition so I could continue installing and investigate the files itself.
But.

Re: Is anyone else having zstd decompression/checksum issues?
If at this point you give the system a moment and try to "pacman -S qt6-declarative", do you end up w/ the same error?
md5sum /var/cache/pacman/pkg/qt6-declarative*If the package is ok it's either your CPU, RAM or disk.

Neg, installing the package explicitly worked fine.
I have originally attempted install on a gen5 NVMe, but thinking the issue was due to compatibility I moved it over to a Samsung 990 pro and it persisted. I've already run through three separate pairs of DDR5 with the same issues, BIOs is at stock.
Which leads me to: I'm using a 13900ks for cpu, and given the plethora of persistent issues, and the subsequent dart throwing Intel has tried to rectify said issues; I'm leaning more towards the cpu.
About a week ago I updated to the most recent BIOs on my board (Gigabyte Z790 Aorus Master X), and I guess one of the issues that Intel has finally uncovered was a flaw in their eTVB microcode lib/algorithm. Which was part of the reason why I labeled my post the way I did. Because if they changed something in the microcode that isn't sympotico with some of the compression libs I shouldn't be the only one running into this, if that new microcode has found its' way into Arch's repo by now. What's more likely is a mixture of the reactionary BIOs updates along with anything upstream trying to fix the issues.

Solid article - Thank you for posting.
I attempted the workarounds stated in the article (which, ironically move away from the "default settings" it originally recommends) to no avail. And further, that article was published in April, and Gigayte has published two BIOs since then trying to alleviate the problem. The last thing I want to do is RMA the cpu, for obvious reasons. But I'll keep my ear to the ground to see if anyone else has the same issues as I find it atypical that their "fix" is now breaking more hardware than fixing, or now rendering what were working cpu's to barely working cpu's. Does Arch pull in cpu microcode from the Linux repo or straight from Intel? I'd be interested to take a peek at the diff from the last couple commits to see what changed.
Thank you

Re: Is anyone else having zstd decompression/checksum issues?
See the upstream URL of https://archlinux.org/packages/extra/any/intel-ucode/ - you can also try https://aur.archlinux.org/packages/intel-ucode-git
Can you downgrade the UEFI ansd see whether that stabilizes the situation?

Interestingly enough the last commit, which was more than a month ago, only had a couple lines of code pertaining to Pentium processors. So, my suspicion is that there's some sort of mismatch with what Intel may have shipped to the motherboard manufacturers that hasn't squared with the software components downstream on Linux just yet.
I'm avoiding downgrading the UEFI as my motherboard (and most commercial motherboards still have) had a set of seven vulnerabilities at the UEFI level that were being actively targeted. That, paired with the fact that I also got back up on Windows on this machine and I haven't had it manifest the same issues even under benchmarking conditions, yet. I know it's nuanced, but if the CPU was bad as a piece of hardware on the system it should be manifesting regardless of OS, correct?
I'm also going to clone the intel-ucode-git aur repo to see if I can get a positive reaction and reach out to Intel and Gigabyte today to at least create a ticket and see if they have anything to add.
I appreciate your help, btw.
Thank you

The CPU isn't "a piece of hardware", the microdode patches patch out bugs of the HW 
Also access patterns/stress level (maybe temperature and voltage) matter (causing the non-deterministic behavior)
Have you tried to disable the spectre mitigations?

I have not. And hopefully it will not be necessary; It took a few (4) reboots, but cloning and then makepkg'ing the intel-ucode-git package seems to alleviate the teethy part of the issues. Or it could be a combination of the settings I've changed as well as the aur version of the ucode.
For future reference is anyone in the future stumbles across this, and take these all with a grain of salt since I'm unsure what the secret sauce actually was. But:
Disabled "Intel Default Settings"
Increased load line to turbo (for all three loadline calibrations)
Set VCORE to adaptive
Increased VCORE offset +.010
Increased ring offset +.010
Increased E core (atom) frequency to 45 across all cores (was 43)
Enabled AVX2 with an offset of 2
RAM at JEDEC
Enabled thermal protection
Enabled hyperthreading
Enabled undervolt protection
As well as a few other ancillary settings that are default on even by Intel's "default" settings, but I'm going to have to edit into this here when i remember or when i reboot to double check.
I've since been able to reinstall all packages and get through 7z benchmarks without decoding errors, as well as get through compressing initramfs without module decompression issues.
Hopefully I'm not taking a victory lap too soon; will update if this ends up just being a fluke.
Thanks again for the help.
