ad0: WARNING - WRITE_MUL write data underrun

[Mark Knight]

Current from approximately 0500 BST on 16th September is giving me 
errors like this from boot:

ad0: WARNING - WRITE_MUL write data underrun 8192>2048
ad0: WARNING - WRITE_MUL write data underrun 8192>6144
ad0: WARNING - WRITE_MUL write data underrun 8192>4096
ad0: WARNING - WRITE_MUL write data underrun 8192>4096

dmesg output can be viewed here:

Any thoughts?  Does this imply data corruption?

Cheers,
