find attached the debug data:

  ethtool.dump.eth0.before
  ethtool.dump.eth0.after
  ethtool.dump.eth0.after2
  boot.log
  config

the 'before' dump is before the hang, shortly after bootup. It also 
includes 'ifconfig eth0' output.

the 'after' dump is after the hang - while the interface is hung.

'after2' dump is after a 'service network restart' - which brought the 
interface back.

Note if i wait long enough (half an hour or so), then not even 'service 
network restart' will bring back the device.

The kernel i tested is: v2.6.29-rc2-13-gf3b8436
