arpresolve: can't allocate llinfo for 192.168.0.1

Hi,

sometimes (not every time) I have problems with networking right after
booting my desktop.

The NIC (re) is usable, because my IPv6 services are accessible, but
IPv4 is unroutable.

In syslog there are these two lines (multiple repeats):

IPv4 address: "192.168.0.1" is not on the network
arpresolve: can't allocate llinfo for 192.168.0.1


I can fix the situation by these commands:

# ifconfig re0 192.168.0.12
# route add default 129.168.0.1

This has happened two times on my PC so far. I'm not totally sure, but
I've seen this problem the first time with a kernel from March 9th.

NIC is:
re0_at_pci0:4:0:0:	class=0x020000 card=0xe0001458 chip=0x816810ec
rev=0x01 hdr=0x00 vendor     = 'Realtek Semiconductor'
    device     = 'RTL8168/8111 PCI-E Gigabit Ethernet NIC'
    class      = network
    subclass   = ethernet

ifconfig (while working):
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500
options=389b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC>
