AMD SB850 Raid - Should an output like this happen?

Hello,

I have a RAID10 setup on my AMD SB850 Raid chipset. Well I noticed from
the very beginning issues with dmraid and its outputs.

zusteller ~ # dmraid -r
/dev/sdd: pdc, "pdc_cficbgcda-1", stripe, ok, 1953124992 sectors, data@ 0
/dev/sdc: pdc, "pdc_cficbgcda-1", stripe, ok, 1953124992 sectors, data@ 0
/dev/sdb: pdc, "pdc_cficbgcda-0", stripe, ok, 1953124992 sectors, data@ 0
/dev/sda: pdc, "pdc_cficbgcda-0", stripe, ok, 1953124992 sectors, data@ 0
zusteller ~ # dmraid -s -s pdc_cficbgcda

I am not sure if this is just wrong usage of the dmraid commands or if
there goes something terribly wrong. Any advice?
