It may be hardware problem.
I hit this bug recently :

I just bought a SATA PCI-e expansion card based on the Marvell 9230 chip, and I get the same error. But only with 3.5+ kernels. Both the current 3.5.7 gentoo-sources kernel and the 3.7_rc4 git-sources kernel report the 04 error code now. But if I fall back to an old kernel (2.6.39) then I get no errors whatsoever, and the RAID array comes up.
