Raspberry Pi OS Lite amd64 を入れてRaspberryPi 3 B で起動. apt update && apt upgrade
して再起動時の起動時間.

とりあえず普通に使えそう.寿命はおいおい.
Raspberry Pi OS で apt update && apt upgrade
して,パッケージを数個導入,Tailscale を導入して再起動して起動しなくなる.
PCに刺してもデバイス自体を認識しなくなった.以下はその時のdmesg.

という感じで数日で動かなくなった,実質数時間.
購入した店舗にレシートと一緒に持参したところ確認無しで交換してもらえた. 次は何日持つか…….
