Hi,

I am seeing some problems with one of my Dell PowerEdge 2950's (running 
RELENG_6_2) on board bce NICs.  The interface seems to crash with the 
following errors, to which the fix seems to be and "ifconfig bce0 down; 
ifconfig bce0 up":

Jun  7 12:20:29 gonzo kernel: bce0: discard frame w/o leading ethernet 
header (len 4294967292 pkt len 4294967292)
Jun  7 12:20:29 gonzo last message repeated 54 times
Jun  7 12:20:58 gonzo kernel: nfs server nfs-server:/usr/home: not 
responding


Is this a know problem? If so is there a solution?

Tom
