--- Comment #11 from tom at unhooked.net ---
This started happening on a couple of my boxes as well. (optiplex 7010, lenovo
thinkcentre m90p) 

em0: TX(0) desc avail = 41, pidx = 788
link state changed to down
em0: link state changed to DOWN
em0: TX(0) desc avail = 1024, pidx = 0
em0: TX(0) desc avail = 1024, pidx = 0

dell -
em0 at pci0:0:25:0:        class=0x020000 card=0x052c1028 chip=0x15028086 rev=0x04
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82579LM Gigabit Network Connection (Lewisville)'
    class      = network
    subclass   = ethernet

No panic, no other messages other than "kernel out of bufferspace" 
I've added -tso -lro -rxcsum -txcsum to ifconfig and we'll see if it stops
puking. It usually takes a couple of days to trigger it. 

Didn't start happening on the dell till last week.
