It took awhile, but the problem re-occured with an upstream kernel --

administrator at stein:/var/log$ uname -a
Linux stein 2.6.35-999-generic #201007081234 SMP Thu Jul 8 11:37:16 UTC 2010 x86_64 GNU/Linux                      
administrator at stein:/var/log$                                                                                      

This is the kernel log from failure to back online:

The same sequence, ifconfig down, rmmod, modprobe, ifconfig up, was used to recover.

** Tags removed: needs-upstream-testing

** Description changed:

  At seemingly random times, a "hw csum error" is reported on the system
  console.  When this happens, the NIC will stop responding.  The sequence
  "ifconfig down, rmmod sky2; modprobe sky2; ifconfig up" will bring the
  NIC back to a normal state.  There does not seem to be any correlation
  between this error and network traffic.  The system this is occuring on
  is a NFS server and can server many GB of data with no problem.
