  tg3: reports "eth0: DMA Status error.  Resetting chip.", fails to work

Bug description:
  I recently upgraded a Hewlett-Packard ProLiant DL385 G1 to precise
  from lucid, landing on linux-image-3.2.0-24-generic 3.2.0-24.39.

  When I rebooted, I was unable to log in over the network.  I examined
  the serial console and found the following (full dmesg attached).
  This sequence  is emitted over and over until "ifdown eth0" is run.

  tg3 0000:03:06.0: eth0: DMA Status error.  Resetting chip.
  tg3 0000:03:06.0: eth0: 0x00000000: 0x164814e4, 0x22b00146, 0x02000010, 0x00804010
  <many lines removed - see attached dmesg>
  tg3 0000:03:06.0: eth0: 0x00007010: 0x44ea66f0, 0x00014a00, 0x009f0020, 0xa184a053
  tg3 0000:03:06.0: eth0: 0: Host status block [00000007:00000001:(0000:0000:0000):(0000:0000)]
  tg3 0000:03:06.0: eth0: 0: NAPI info [00000000:00000001:(0000:0000:01ff):0000:(00c8:0000:0000:0000)]
  tg3 0000:03:06.0: tg3_stop_block timed out, ofs=4800 enable_bit=2

  The problem (or a very similar one) is also present in oneiric's
  kernel (I tested linux-image-3.0.0-20-server 3.0.0-20.34).
