I have the same problem on Maverick beta, and it's can be reproduced on a
VMware machine:
How reproducible: always
How to reproduce:
1. Download Maverick beta ubuntu-10.10-beta-server-i386.iso from
http://www.ubuntu.com/testing/download
2. Boot it on VMware machine (mine is VMware workstation 7.1.0 build-261024)
3. Choose "Try Ubuntu", then open the terminal, become root by "sudo -i"
4. Run: lshw -businfo -class network
5. Then it shows me: "Killeduffer devices"
and I can see the kernel oops by running "dmesg":
