Hi, I am getting the following error while booting kernel on upstream commit a49a9dcce802b3651013f659813df1361d306172, config is attached. Seems there is some kind of resource leak. Thanks ------------[ cut here ]------------ ODEBUG: free active (active state 0) object type: timer_list hint: delayed_work_timer_fn+0x0/0x6e kernel/workqueue.c:4923 WARNING: CPU: 0 PID: 1 at lib/debugobjects.c:329 debug_print_object+0x164/0x17c lib/debugobjects.c:326 Kernel panic - not syncing: panic_on_warn set ...
