I recently installed 7.0-RELEASE, and have recently started seeing 
these in my kernel log:

g_vfs_done():ad2s1a[WRITE(offset=19671924736, length=131072)]error = 5
ad2: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=71976351
ad2: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=36619199
ad2: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=36638271
ad2: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=36638271
ad2: FAILURE - WRITE_DMA status=51<READY,DSC,ERROR> 
error=84<ICRC,ABORTED> LBA=36638271
g_vfs_done():ad2s1a[WRITE(offset=1578893312, length=131072)]error = 5

I suspect that the errors are not associated with the upgrade (i.e., 
coincidence). Are they serious, or just something that is being 
reported in v7 that wasn't being reported in v5.1?
