I believe that I have configured everything correctly for the iop-adma
acceleration on iop13xx, using kernel 2.6.39, but I notice that the pq
self test is failing:

iop-adma iop-adma.0: Intel(R) IOP: ( xor xor_val fill cpy intr )
iop-adma iop-adma.1: Intel(R) IOP: ( xor xor_val fill cpy intr )
iop-adma iop-adma.2: Self-test pq-zero-sum failed to validate: 1

The relevant bits from the kernel configuration are:

CONFIG_MD=y
CONFIG_BLK_DEV_MD=y
CONFIG_RAID_ATTRS=m
CONFIG_MD_RAID0=y
CONFIG_MD_RAID1=y
# CONFIG_MD_RAID10 is not set
CONFIG_MD_RAID456=y
# CONFIG_ASYNC_RAID6_TEST is not set
CONFIG_ASYNC_RAID6_RECOV=y
CONFIG_RAID6_PQ=y

Is this a known issue?  We have previously been using the iop-adma
acceleration on 2.6.26, but this was prior to the pq self-test being
added.
