FreeBSD 5.3: panic page fault with nge driver

[sp0ng3b0b]

I've been told that this might be fixed in CURRENT. That's nice, but I 
am trying to run a production quality server and CURRENT is not 
recommended for that purpose. Any recommendations?

By the way, is Questions the wrong list for my problem?
