The issue is that we\nalready freed the completion context in polling/interrupts handler which\nmeans we print data from context in an unknown state (it might be\nalready used again).\nChange the admin submission flow so alloc/dealloc of the context will be\nsymmetric and dealloc will be called after any potential use of the\ncontext.",
