Comment 6 for bug 1005226

I've just tried the 3.4-quantal kernel [ http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/linux-image-3.4.0-030400-generic_3.4.0-030400.201205221131_amd64.deb ], and the issue persists that devices attached to the Marvell controller fail to be recognized with IOMMU enabled. Removing tag 'needs-upstream-testing', and marking as 'kernel-bug-exists-upstream', as requested.
