FWIW, I've been seeing the same problem---WRITE_DMA timeouts on
ad4 and ad6, and both write and read timeouts on ad0.  The problem
occurs for 6-CURRENT as of 9/14.  It does not occur for BETA4.
I can try to narrow this down further if needed.  Here's some
information about the machine, which has ad4 and ad6 mirrored via ccd(4):
