![]() The emulated UART in the Firecracker VMM (aka the implementation in the rust-vmm/vm-superio project) includes FIFOs but does not implement the FCR register, which is used by ns8250_flush to flush the FIFOs. Check the LSR to see if there is still data in the FIFOs and call ns8250_drain if necessary.
