Comment 66 for bug 245779

I am encountering soft lockups related the bond module. I suspect they are related however this situation is a bit different.

This server is dedicated, no virtualization, host or guest, here.

cat /proc/version_signature
Ubuntu 2.6.24-24.60-server

This unit runs bonding on 2 x Intel e1000 interfaces and serves up ISO and OVF files via NFS off a RAID6 array of 4 drives for use by VMWare ESXi clients.

This server is dedicated, no virtualization, host or guest, here.
