Comment(by wad):

 dsd,
    Yes, the thing it is chocking on is the WiFi card.  I removed the Wifi
 cards from two B2s, and they haven't crashed yet (5400 and 2300 cycles).
 I also performed the WLAN PWR ECO on two laptops (which keeps the WLAN
 powered in suspend) and they haven't crashed either (although they haven't
 run enough to be conclusive.)

 BTW, I am simultaneously running my SD wear testing at the same time on
 all these machines.  So far, I haven't seen any errors generated in the
 suspend/resume testing.
