I have 6.1-RELEASE installed on a Supermicro SuperServer 6014P-TR
with Supermicro motherboard: Super X6DHP-TG

I have four SATA drives attached to the internal backplane which uses
the following controller, I am Not using the onboard RAID features:
Marvell 88SX6081 4-port SATA Controller with 3rd-Party Adaptec
AIC-8110(4x drive), RAID 0, 1, JBOD support
The problem I am seeing occurs with the fourth drive, ad10, and appears
on all read/write operations:
ad10: WARNING - WRITE_DMA48 soft error (ECC corrected) LBA=293046767
kernel:ad10: WARNING - WRITE_DMA soft error (ECC corrected) LBA=12393823
kernel:ad10: WARNING - READ_DMA soft error (ECC corrected) LBA=12480567
This same warning message appears on 6.0-RELEASE and 6.1-STABLE
I have problems with a similar chassis w/ SCSI and bay 3 throwing
spurious errors on a number of systems, so I think its just poor
backplane design on SuperMicro's part. Try getting them to replace
your backplane board.
I am going to RMA the backplane and its composite SATA cable. I'll see
if that makes a difference. Obviously not ideal, but how serious do you
think these ECC warnings are, data lose, system stability?
Thanks
