DMA error on NIC card

We are getting occasionally the following error (Pfsense 2.2.5-RELEASE (amd64) )
alc0: DMA read error - resetting
alc0 : could not disable RxQ/TxQ ( 0x00000008)
alc0: could not disable Rx/Tx Mac (0x00000008)
What does this error indicate and is it critical and how can we fix it?
