Comment 9 for bug 800527

I've only had access to 32-bit installs so far, with which this error looks fairly innocuous (looks like the dev argument isn't used to establish mappings on 32-bit). However, on 64-bit, it appears that the incorrect dev pointer code causes an oops (specified in bug 659348).

I've put a call for testing on that bug, that should show a fix with the -proposed kernel.
