It happens only occasionally, and only when streaming data over NFS (2-3Mbps tx from the N2). Usually when streaming data over long periods of time (watching a movie). The dmesg message I get (logged over netconsole, which still works) is:
Code: Select all

The funny thing is - this lock-up happened to me twice in the past month, though never before on the same N1, running the same kernel for about 6 months...
I've searched the forums, and others had similar issues that were solved at the nic driver level:
Not sure if the nic on the N1 suffers from the same problem, but I wanted to ask the few N1 users around if you've ever seen this with your systems?
