I too see checksum errors ocurring for the first time using OpenSolaris 2009.06

I see the problem occur within a mirrored boot pool (rpool) using SSDs.
Hardware is AMD BE-2350 (ECC) processor with 4GB ECC memory on MCP55 chipset,
although SATA is using mpt driver on a SuperMicro AOC-USAS-L8i controller card.

Boy, that looks familiar. Did you try zcksummon to see if the checksums are
really being fixed? If it is the same problem I encountered, then they are
not, even though the scrub says no errors (and the problem goes back before
snv100). Your hardware seems pretty beefy, though. Note that iostat -Ene
never reported any hard errors in my case even though the mobo was known to
have problems, so hard errors do not explain the problem.
