System Reboots After Shutdown on Acer

[S_Mosin]

Hello everyone, i got issue with my system - after updating to Tumbleweed 20250606 (6.15.0 kernel) when i click on Shutdown button in kde session screen system shutdowns but rebooting again. i dont know whats a problem - w/ bios or kernel…
in bios common reasons of this behavior like wake-on-lan n fastboot are disabled. The journalctl -b -1 -e says next:

I had a similar issue on an Acer laptop some time ago and it was an issue with one of the USB ports which had a mouse plugged in, using a different port and the issue went away!

Just in case it helps…

After reboot via physical power button problem run away - maybe issue was with bios cuz after detecting problem i saw changed time in bios and OS.

maybe this thread will be helpful to others who getting same problem
