This would be on a kernel that exhibits the problem. That failed, but I don't think we really know why. We tried to test that theory with, a patch intended to reset the LSI device after changing the BARs.
That seems like a plausible theory to me. Yinghai's theory is that the LSI device has firmware that caches the BAR values, and it doesn't notice when Linux changes the BARs. Starting with your 3.4.1 kernel, Linux tries to assign space for the SR-IOV BARs, and in the process, it moves the regular BARs as well: The BIOS on your platform assigns space for the regular BARs, but not for the SR-IOV BARs: The LSI SAS2008 has an SR-IOV capability.
