I've got 4 Tyan S2882s. The units I use the GigE (bge) on crash all the 
time while syncing or running ggated... Not particularly heavily loaded 
either (avg of .5 maybe?)

The other one that doesn't use GigE (www.UserFriendly.org) has never 
crashed.

It's NICs I'm pretty sure. We've used various stages of 5.3 and 5.4 to 
no avail. I'm about to start RMA'ing them... but when all 3 die the same 
way... I'm not encouraged.

Presently we're running ggates across the fxp cards and they've been 
solid (so far... we only started yesterday)
Are you using the onboard bge or PCI em?
