We've got five 5015M-MT+'s in production.  The PDSMI+ motherboard has 
two 82573's, one of which has a known EEPROM issue that Jack Vogel has 
sent a DOS-based utility around to fix up (search the archives for 
dcgdis.exe).  It fixed watchdog timeouts I was having way back in the 
6.2 beta cycle -- in my case they only happened when I had link at 1G 
and went away if I dropped to 100M.  It might be worth ruling that out 
first unless you've already done that. :)

I haven't tried the 6.6.6 driver on mine yet, though, so this could be 
something totally different.  I was going to bump one of them from 
RELENG_6 to RELENG_7 as a test soon.
