from bugzilla.kernel.org - data corruption with Opteron CPUs and nvidia chipsets//memory hole mapping / iommu related bug

[Brian Murray]

Binary package hint: linux-source-2.6.15

This has been fixed upstream and in gutsy with git commit cf6387daf8858bdcb3e123034ca422e8979d73f1 . It looks like a small patch and should be incorporated into dapper-updates if possible.

I've experienced a similar issue together with the iommu bug, but iommu=soft doesn't resolve it: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/129260

Fixed kernel is in dapper-updates now. Nobody was able to verify, though, so please reopen if you still have problems.
