Ubuntu Studio 20.04 LTS с двойной загрузкой, с / Root на SSD и / Home на жестком диске. графика nVidia. На выключение уходит десять минут. Почему?

Иногда мой ноутбук выключается нормально, но в шести из десяти случаев на выключение уходит десять минут.На экране находится логотип Ubuntu Studio и вращающееся колесо. При нажатии Esc на дисплее отображается:

Reached target Shutdown.
Reached target Final step.
Finished Power-Off.
Reached target Power-Off.

Все, как ожидалось, затем через некоторое время он переходит в повторяющуюся процедуру

systemd-shutdown[1]: Syncing filesystems and block devices - timed out, issuing SIGKILL to PID 2290

Затем много строк, например:

nvme nvme0: I/O 510 QID 8 timeout, reset controller
Waiting for process: systemd-journal, (sd-sync)

Машина выполняет несколько циклов сообщений об ошибках на нескольких страницах перед тем, как в конечном итоге выключиться.

Я пробовал Alt SysRq REISUB, но машина не перезагружается без жесткого отключения питания, когда слышно, как жесткий диск скользит до остановки, что устанавливает мои зубы на грани.

Принудительное выключение питания во время сообщений об ошибках вызывает ту же проблему с жестким диском / зубьями.

Загрузка проходит нормально и быстро.

Любой совет будет очень признателен.

Изменить: Тема Как диагностировать зависание при выключении? не отвечает на мой вопрос. В отличие от этого поста, я могу увидеть процесс завершения работы, просто нажав Esc , когда включен экран-заставка завершения работы. Я также слышу активность жесткого диска.

Мне удалось сфотографировать экран за мгновение до выключения ноутбука:

Сообщения о выключении

Примеры сообщений такие:

[641.546916] Buffer I/O error on dev nvme0n1p6, logical block 13...
and
[641.550604] EXT4-fs warning (device nvme0n1p6): ext4_end_bio:30...
and

Устройство nvme0n1 - SSD, p6 - это место, где установлен /. Значит ошибка где-то есть. Может быть, неисправный SSD?

Редактировать: Из / var / log / syslog Это нормальное завершение работы. Это происходит в 12:21:02. Затем компьютер перезагружается в 12:22:44.
