  • Switching ttys wouldn’t have done anything. The kernel logs are usually saved to efi_pstore (or sometimes erst) by default though.

    Edit: you can also set drm.panic_screen=kmsg as a kernel parameter to print the logs instead of the QR.

  • Nah, when a kernel panic hits then everything’s screwed.

    Pressing ESC does work for systemd-bsod (which is different) and as you mentioned Plymouth; but not drm_panic.

  • Edit: yes, it was Systemd who implemented it.

    Nah, systemd-bsod is different and designed to show info about boot failures:

    It’s rather quite useless.

    drm_panic on the other hand has nothing to do with systemd, and is what’s shown in OPs post. The link can be quite useful for users to post their issues on bug reports or whatever. But if you know what you’re doing, then it’s pretty easy to configure it to print text instead.

    Also remember, the reason drm_panic exists is because graphical outputs would otherwise freeze during a kernel panic, and not show anything useful.

  • This probably isn’t too useful for you as they only have 24v and 54v models, but Ubiquiti used to make EdgePower UPSes. They have a http management interface that lets you monitor the power usage or power cycle the router if a ping stops responding, and etc. I installed one recently for a POE switch of mine.
