aac/fxp system instability

[al at xms.co.za]

Hi,

I'm running two Intel (fxp) NICs in a Dell PowerEdge 2650 destined for use 
as a firewall/mail filter etc. I got these because the re & bge drivers 
didn't support ALTQ, which we need.

Problem is, when I run ifconfig on one of the fxp cards, the aac driver 
hangs and the system crashes. Complains something about a 
NMI_SECONDARY_ATU_ERROR, then increasingly long timeouts, while system 
hangs.

I'm running FreeBSD 5.3-RELEASE-p5.

Erm, oh dear... ;)
