Comment 3 for bug 398392

Interface eth0 was active, I added the sources mail repos to package manager, and I hitted "reload" button in synaptic package manager.
Therefore the system was busy downloading data from ubuntu servers.
The download speed was about 70KB/s.

While this was in progress, I activated the md array involving the three disks connected to the three sata cards.
As soon as the array was assembled and started, the system freezed.

Note that eth0 is sharing an interrupt with a sata_via module.
