Now tested:
e1000e.TxIntDelay=0,0,0,0
[    4.930570] e1000e 0000:04:00.0: (unregistered net_device): Transmit 
Interrupt Delay set to 0
[    4.930573] e1000e 0000:04:00.0: (unregistered net_device): 
Interrupt Throttling Rate (ints/sec) set to dynamic conservative mode
Problem still occur.

e1000e.TxIntDelay=0,0,0,0 e1000e.InterruptThrottleRate=0,0,0,0
[    4.971476] e1000e 0000:04:00.0: (unregistered net_device): Transmit 
Interrupt Delay set to 0
[    4.971478] e1000e 0000:04:00.0: (unregistered net_device): 
Interrupt Throttling Rate (ints/sec) turned off
Problem also occur.

Probably it is a case of this specific machine, this problem is 
happened on same hardware (Sun Fire X4150).
The only "exotic" thing here is set of cards:
04:00.0 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit 
Ethernet Controller (Copper) (rev 01)
04:00.1 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit 
Ethernet Controller (Copper) (rev 01)
0b:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet 
Controller (rev 06)
0b:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet 
Controller (rev 06)

I'm using first card.
