@chinhhut Ah ok, an error during shutdown... well I never experienced such issue, may be an error in the kernel or in the trust OS which is leading some spurious interrupt after secondary cores are brought down... I'm not able to recognize anything specific from that crash dump, but I may suggest you do add "panic=10" in the kernel command line: this way, when a kernel panic happens, the kernel may still try to reboot after 10 seconds so you don't get stuck.
