...which seems to have been fixed by some major [1]changes to vr(4)
almost a year ago.  Or at least the driver notices the problem and

    vr0: vr_link_task: Tx/Rx shutdown error -- resetting
    vr0: restarting
    vr0: vr_stop: Rx shutdown error
    vr0: Using force reset command.

IIUC this change has been MFC to 7.1.  Actually I tested it with pfSense
1.2.2 which (according to dmesg) is 7.0 but nevertheless they seem to
have the fixed driver.  I wonder whether they back-ported it themselves
or if there's a patch available.  Of course I'd be interested in seeing
such a patch for 6.3 and thus for m0n0wall... ;-)

BTW, is it still possible to build a custom m0n0wall image and upload it
using the firmware upload mechanism?  Or will it be rejected because
it's not signed?

Cheers, Jukka
