 I have a similar problem with bce driver on FreeBSD 6.1-stable. I tried it with and without 
 SMP with the same result. The machine does not freeze, only the network interface goes 
 up/down which makes the whole system unusable:

 It usually works for some time (hours)  after reboot before it starts happening.
 
 Coincidentally, the machine I have is also Dell PowerEdge 1950 with dual Broadcom 
 NetXtreme II BCM5708C 1000Base-T interfaces (bot only one is configured currently).
 
 I saw a similar error mentioned elsewhere in other lists. E.g. check freebsd-current:
 
 http://lists.freebsd.org/pipermail/freebsd-current/2006-August/065001.html
 
 Another things I noticed (which may or may not be related, but is worth mentioning as it 
 involes ACPI) is that sometimes the machine does not reboot on "reboot" command, instead 
 it seems to be staying in halted state.
