    Honestly I’ll just send it back at this point. I have kernel panics that point to at least two of the cores being bad. Which would explain the sporadic nature of the errors. Also why memcheck ran fine because it only uses the first core by default. Too bad I haven’t thought about it when running memtest because it lets you select cores explicitly.

    This sounds like my best shot, thank you.

    I’ve installed the amd-ucode package. It already adds microcode to the HOOKS array in /etc/mkinitcpio.conf and runs mkinitcpio -P but I’ve moved microcode before autodetect so it bundles code for all CPUs not just for the current one (to have it ready when I swap) and re-ran mkinitcpio -P. Also had to re-run grub-mkconfig -o /boot/grub/grub.cfg.

    I’ve seen the message “Early uncompressed CPIO image generation successful” pass by, and lsinitcpio --early /boot/initramfs-6.12-x86_64.img|grep micro shows kernel/x86/microcode/AuthenticAMD.bin, there’s a /boot/amd-ucode.img, and an initrd parameter for it in grub.cfg. I’ve also confirmed that /usr/lib/firmware/amd-ucode/README lists an update for that new CPU (and for the current one, speaking of which).

    Now from what I understand all I have to do is reboot and the early stage will apply the update?

    Any idea what it looks like when it applies the microcode? Will it appear in dmesg after boot or is it something that happens too early in the boot process?

    All hardware is the same, I’m trying to upgrade from a Ryzen 3100 so everything should be compatible. Both old and new CPU have a 65W TDP.

    I’m on Manjaro, everything is up to date, kernel is 6.12.17.

    Memory runs at 2133 MHz, same as for the other CPU. I usually don’t tweak BIOS much if at all from the default settings, just change the boot drive and stuff like “don’t show full logo at startup”.

    I’ve add some voltage readings in the post and answered some other posts here.

    Motherboard is a Gigabyte B450 Aorus M. It’s fully updated and support for this particular CPU is explicitly listed in a past revision of the mobo firmware.

    Manual doesn’t list any specific CPU settings but their website says stepping A0, and that’s what the defaults were setting. Also I got “core speed: 400 MHz”, “multiplier: x 4.0 (14-36)”.

    even some normal batch cpus might sometimes require a bit more (or less) juice or a system tweak

    What does that involve? I wouldn’t know where to begin changing voltages or other parameters. I suspect I shouldn’t just faff about in the BIOS and hope for the best. :/








  • override the auto driving

    I must be tired right now but I don’t see how a remote operator could have driven better in this situation.

    You can’t get away from someone blocking your car in traffic without risk.of hitting them or other people or vehicles.

    You probably meant they ought to drive away regardless of what they hit, if it helps the passenger escape a.dire.situation? But I have to wonder if a remote operator would agree to be put on the spot like that.



  • The safest method, if your /home has enough space, is to use it instead of /var for (some) Flatpak installs. You can force any Flatpak install to go to /home by adding --user to the command.

    If you look at the output of flatpak list it will tell you which package is installed in user home dir and which in system (/var). You can also show the size of each package with flatpak list --columns=name,application,version,size,installation.

    I don’t think you can move installed apps directly between system/user like Steam can (Flatpak is REALLY overdue for a good package manager) but you can uninstall apps from system, then run flatpak remove --unused, then install them again with --user.

    Please note that apps installed with --user are only seen by the user that installed them. Also you’ll have to cleanup separately for system and user(s) in the future (flatpak remove --unused for system, then flatpak remove --unused --user for each user).

    Interesting, I’ll keep it in mind.

    Still not sure it would help in all cases. Particularly when 3rd party repos have to override core packages because they need to be patched to support whatever they’re installing. Which is another very bad practice in the Ubuntu/Debian world, granted.
