The changes to copy_thread() made in commit eed7c420aac7 ("powerpc:

When in consumer mode with BCLK disabled (FSL_SAI_CSR_BCE = 0) the
FIFO's can still contain data when resumed. It might also be possible
with BCLK enabled but just less likely.
When the FIFO's still contain data on resume it can cause channel
shifting on e.g. XRUNS. A Software Reset will reset the
