Is there a decent way to debug a Linux laptop that occasionally completely freezes for 1-5 minutes and then returns to normal?

No video. If gnome-system-monitor was running, its graph just pauses updating through the whole pause. compiles/rsyncs make no progress.

Sometimes there's a systemd-journald SIGABRT crash dialog (Ubuntu's reporting stuff) after the pause happens; that's my best clue so far.

But bugzilla.redhat.com/show_bug… suggests the systemd-journald crash is a symptom rather than a cause.
