Bugzilla – Bug 1183210
Rebooting instead of shutdown
Last modified: 2021-05-29 00:47:59 UTC
problem: This laptop is a Dell G5 15 5505 SE (AMD). previously I was on kernel 5.10 and yesterday updated(zypper dup) to the kernel 5.11. now after doing the power off system automatically restarts.
It's often some device power management, such as the ethernet WoL, or USB or ACPI wakeup. Check the content of /proc/acpi/wakeup, and try to disable the "enabled" entries; e.g. if the entry "XHC" shows "enabled", write like: echo -n XHC > /proc/acpi/wakeup For WoL, you can check and toggle WoL. See the manpage for details. Those aren't meant as a fix, of course, but we need to identify the cause at first.
