The submitter emailed me privately today asking about the atl1 DMA bug.
The instant bugzilla is the apparent result of our exchange.  

I replied to the private inquiry thusly:

A workaround is in place in the -mm kernel tree.

I expect it will be pushed into the 2.6.24 kernel series.

Fedora intends to pick up the patch for F7 in the near future.

Even without the patch, you can boot with mem=3900 on the kernel
command line and you won't hit the problem.

In related news, Jeff appears poised to push the patch (with
loathing) into netdev.
