  • A few decades ago I bought a used IBM as a *nix server, but it would lock up at nearly random intervals like you describe. Tried a different Linux distro… same issues. Tried BSD - same issues!

    It wasn’t until after I learned of the 1999-2007 capacitor plague that I inspected the motherboard and saw that yes, several of the capacitories were bulging.

    I mailed the motherboard to a servicer who replaced all the capacitors for a nominal fee. After that it was a rock solid system. You mention that this is recent hardware, but I would still suggest taking a peek at those caps.











  • I’m using Gentoo with systemd and a customized kernel, and additionally I have the /usr partition LUKS encrypted. Because /usr is absolutely essential for systemd to function, I configured dracut to make a specially crafted initrd which activates the luks lvm and prompts for the password to decrypt and mount /usr on startup before systemd init tries to run.

    About a year or two ago, some update to dracut or some other dependency (assumption) caused the dracut generated initrd’s to kernel panic. After multiple days of troubleshooting, I discovered that just copying forward an older initrd in /boot and naming it to match the new kernel, e.g. initramfs-6.6.38-gentoo.img , allows the system to boot normally .

    So, my Gentoo is booting a kernel 6.6.something with a ramdisk generated in the 5.9 kernel era. I am dreading the day when this behavior breaks and I can no longer update my kernel 😳
