SATA Error

[Dave Stephens]

OS Version:  FreeBSD 6.1

What appears to be repeated failures keep occurring with the SATA
drive or controller in my server.    The error is a series of 3
repeated messages where the only difference appears to be the offset
and the LBA.  All of the hardware in this server is brand new and is
not believed to be in faulty.  If anyone could tell me what is going
on with this, or if it is a known issue point me at how I might patch
something or otherwise fix it.  The server does not go down after the
error, but the error is disconcerting none the less and leaves me
worrying about hard drive data integrity.

Sample Error Message......
--------------------------------------------------

g_vfs_done() : ad8s4e[WRITE(offset=59959787520, length=131072)]error=5

ad8: FAILURE - WRITE_DMA48 status=51 <READY,DSC,ERROR> error=10

Here is some related info cut out of dmesg.....

Note that atapci1 is built onto the motherboard and doesn't seem to be
supported by FreeBSD at this time (no HDDs can be found during install
when they are attached to it.)
