關機並重啟掛起

我的電腦 10 次中有 9 次需要 ≅ 2 分鐘才能關閉或重新啟動。我嘗試了很多事情，比如添加systemd和/或shutdown到 initcpio 鉤子，但沒有運氣。

reboot -f永遠不會掛起，所以我按照這些步驟進行調試。添加選項*/proc/cmdline*後變為

initrd=\intel-ucode.img initrd=\initramfs-linux.img root=PARTUUID=d596f77d-aafa-479f-ad3c-df9e7c91fc7b rw quiet systemd.log_level=debug systemd.log_target=kmsg log_buf_len=1M printk.devkmsg=on enforcing=0

和debug.sh

#!/bin/sh
mount -o remount,rw /
dmesg > /shutdown-log.txt
mount -o remount,ro /

令我驚訝的是，這大大減少了掛起的次數，但我設法在重新啟動時填寫了shutdown-log.txt：https ://gist.github.com/MatTheCat/99498b006651110462f3488dcb454b40

這是重新啟動正常時的shutdown-log.txt ： https ://gist.github.com/MatTheCat/77f168927008bb0b886bb944d19337f1

電腦是戴爾 XPS 13 9380。

似乎匹配https://bugs.archlinux.org/index.php?do=details&task_id=50420因為

[ 2144.333960] systemd-shutdown[1]: Sending SIGTERM to remaining
...
[ 2234.342297] systemd-shutdown[1]: Sending SIGKILL to PID 306 (lvmetad).

調查。

設置use_lvmetad為而0不是*/etc/lvm/lvm.conf*可以解決此問題。我不知道發生了什麼，所以我只希望這不會引起任何問題，因為我沒有使用 LVM。1

我仍然願意接受任何解釋。

自從我寫這篇文章以來已經有一段時間了，所以我試圖重置use_lvmetad.

$ lvm version
 LVM version:     2.02.185(2) (2019-05-13)
 Library version: 1.02.158 (2019-05-13)
 Driver version:  4.40.0

$ systemctl --version
systemd 242 (242.84-1-arch)

大約十次重新啟動後看不到任何問題。保持我的手指交叉。
