The EFI console output call return with interrput enabled, it is a firmware bug. And there was a solution that disabled interrupt it return right away. But in some case the interrupt could happen during the efi call context. If an interrupt was handled, a printk call again will make it re-entried, or a swap might be happens. This is suggested solution appiled for EFI console output: 1. Skip printk call when it is called in interrupt context. 2. Disable the schedule during the EFI call window.
