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．
[ +2.168700] Bluetooth: hci0: Hardware error 0x0c [ +0.012982] Bluetooth: hci0: Opcode 0x c1a failed: -110 [ +0.000048] Bluetooth: hci0: command 0x0c1a tx timeout [ +0.009918] Bluetooth: hci0: Exception info size mismatch [ +0.001989] Bluetooth: hci0: Opcode 0x200b failed: -16
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……．
