I don't believe this is the same problem. The symptoms in 1774 are
kernel panics with CPU ECC errors, if I'm reading it correctly. The 7768
kernel bug is corrupted 4k blocks in the pagecache, not kernel panics.
Is this replicated on several machines? You could try booting with
iommu=soft, which is the 7768 workaround, but I think that's a long
shot. You might try "noapic", but hardware ECC errors would seem to
point to a timing problem or bad hardware.
