Submitting the same problem. Intrepid amd64 crashes under heavy load & more network connections (samba, ssh, headless virtualbox). Used to be Hardy, but then I performed a dist-upgrade, because the bug occured at Hardy too. Thought it would help :( Sometimes I can push 50 gigs over samba straight, sometimes it crashes after 100 megs. It's an ASUS-M2A-MX board with integrated Attansic (atl1) card and an Intel 1000 (e1000) card. Detailed info enclosed in the attached file. Hope this may help.
