JFTR: Same again today:

tar-over-ssh around 60GB data on 100MBit with about 11MB/sec (10sec
averages!). Very stable.

Switched the webserver-load from the old production server to the
new PE6650, some thousand hits per minute. Worked very stable for about
4 min, then everything was stalled, even ssh.

Rebooted under load, after reboot about 10 minutes until next
network-hangup. Dead.

Switched the load back to the old server (ip-alias).

--> bge0 seems broken on Dell PE6650
--> Will buy some intel GBit NICs now.
