RTM_DESYNC when starting network

trondd-2
Just updated my -current VM hosted in VMware Fusion.  Upon reboot, I got
an em0: RTM_DESYNC and the boot process hung.  After a couple forced
reboots, I figured out that if I "Disconnect Network Adapter" then
reconnect it, booting will continue with the DHCP exchange and all seems
to work fine.

Tim.


From dmesg -s:

starting network
em0: RTM_DESYNC  <-- Hangs here until network disconnect/reconnect
em0: DHCPREQUEST to 255.255.255.255
em0: DHCPACK from 172.25.177.1 (00:10:db:ff:10:02)
em0: bound to 172.25.177.119 -- renewal in 129600 seconds
reordering libraries: done.

This has just been fixed in -current.  Please compile a new kernel or
wait for the next snapshot.
