 Same problem with Asus P5BV-C/4L in production.
 
 I found desktop with Asus P5LD2 MB and use it for experimental setup.
 Three host is same gig switch, msk0 configured with vlans and
 ipforwarding
 For tests I run iperf -c 192.168.4.21 -t 60000 -w 128k -P 4 between
 hosts on different vlans.
 7.2-RELEASE kernel with if_msk* from head +patch. Need to specify
 ifconfig -vlanhwtag  to run without input errors,
 after 30 minutes card locked,  down/up interface not help, need to reboot.
 Next I connect disk witch Ubuntu 9.04, setup vlans, test run ok,
 little lover forwarding rate.
 After, boot again freebsd, run test. Hmm, test run ok...
 Reboot with stock 7.2-REL GENERIC kernel. Box running well over weekend...
