- A major update to the e1000 driver.

- 1394 updates

This release has been working quite well after some initial hiccups (see -mm hotfix), but a couple of hours ago another bad thing (tm) happened.

At the time I was moving 100G of data from one partition on a non-raid partition to a new RAID-1 md that I had created earlier. Both are ext3 partitions.

The word "barrier" of course comes to mind again, I'm not sure NeilB is the culprit this time either but I've cc'd him in just in case.

The file copy went on happily for quite a while (maybe 10 mins or so) under very high IO load before blowing up as below. The terminal was spewing out constant traces but hopefully the right ones are here as these are the first few (if not, I have copied a bit more).
