It wasn't 6.2-BETA it was after the new driver import, around 2 months
ago if I remember correctly. It appears to be only on machines with some
data traffic.

I updated to the 6-STABLE when the new intel driver was imported, after
that the problems started , so my best guess is that it has something to
do with that driver update.

Hope this helps some more (see pciconf for more details about my cards)

pciconf:

em0 at pci0:9:0:   class=0x020000 card=0x11138086 chip=0x10768086 rev=0x00 
hdr=0x00
     vendor   = 'Intel Corporation'
     device   = '82547EI Gigabit Ethernet Controller'
     class    = network
     subclass = ethernet
em1 at pci0:10:0:  class=0x020000 card=0x11138086 chip=0x10768086 rev=0x00 
hdr=0x00
     vendor   = 'Intel Corporation'
     device   = '82547EI Gigabit Ethernet Controller'
     class    = network
     subclass = ethernet
