Long critical section and interrupt latency

A task copies a 2 KB struct inside taskENTER_CRITICAL. A UART at 921600 baud starts losing bytes. Why?

A.Critical sections slow down the clock that drives the UARTB.The copy is moved into a separate task by the kernelC.taskENTER_CRITICAL resets the UART peripheral each timeD.Interrupts up to the syscall priority are masked during the copy
