Wired Ethernet Issue: Connection stops working

[craigbert]

Hello All,

My laptop's NIC is a Marvell 88E8057 PCI-E Gigabit Ethernet Controller. Here recently, for no obvious reason, my ethernet connection just seems to stop working. Sometimes ifconfig eth0 down/up will fix it, but most of the time the reboot will do it. It will continue working for a random amount of time which is usually less than thirty minutes. When I put in my Windows 7 hard drive and the connection stays up without issues. This leads me to believe that it is not hardware related.
Here is the info from ifconfig:

eth0      Link encap:Ethernet  HWaddr f0:bf:97:1d:ae:24  
          inet addr:192.168.1.12  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::f2bf:97ff:fe1d:ae24/64 Scope:Link

          RX bytes:22822 (22.8 KB)  TX bytes:12687 (12.6 KB)
          Interrupt:18

Anyone have any idea about what may be going on?

Need to know which kernel module driver is handling the card. What's the output of

lspci -k

Ah, the dreaded Marvell chip and sky2 driver. Bug reports back to 2007.

Next time you experience the failure, please copy-paste the output of this command:

grep eth0 /var/log/syslog

I want to see what errors may be logged, if any, before I suggest a workaround.
