Everyone:

I just installed FreeBSD 10.0-RELEASE on an Asus EeeBox B202 (which 
comes with Linux). This particular version of the product comes 
with a JMicron gigabit Ethernet adapter that uses the jme(4) 
driver. Because it only has one port and I need several, I've set 
it up with multiple VLANs, which are trunked out to a little 
Netgear VLAN switch.

Unfortunately, the interface is bouncing up and down every few minutes:

Sep 13 12:44:44 <kern.notice> testbed kernel: jme0: link state changed to UP
Sep 13 12:44:44 <kern.notice> testbed kernel: jme0_1: link state changed to UP
Sep 13 12:44:44 <kern.notice> testbed kernel: jme0_2: link state changed to UP
Sep 13 12:44:44 <kern.notice> testbed kernel: jme0_3: link state changed to UP
Sep 13 12:50:04 <kern.notice> testbed kernel: jme0: link state changed to DOWN
Sep 13 12:50:04 <kern.notice> testbed kernel: jme0_1: link state 
changed to DOWN
Sep 13 12:50:04 <kern.notice> testbed kernel: jme0_2: link state 
changed to DOWN
Sep 13 12:50:04 <kern.notice> testbed kernel: jme0_3: link state 
changed to DOWN
Sep 13 12:50:43 <kern.notice> testbed kernel: jme0: link state changed to UP
...

The problem didn't seem to occur with the bundled Linux distro. Has 
anyone else seen this problem? Know of a fix?
