Public bug reported:
Expected result:
Selecting Shut Down from the KDE Plasma application menu should cleanly
terminate running processes and power off the computer.
Actual result:
After selecting Shut Down from the KDE Plasma application menu, the kernel
reported repeated list_del corruption while cleaning up processes. The trace
included list_lru_del_obj, d_lru_del, shrink_dcache_tree, proc_flush_pid, and
release_task.
The shutdown sequence then ended in a kernel panic displaying:
stack-protector: Kernel stack is corrupted in:
list_lru_walk_node+0x200/0x200
The computer did not power off and required a manual reboot/power cycle.
