    sorry for taking so long to get back. busy problematic times.

    the dumps and ifconfigs are a bit less 'clean' because the router
    serves several other computers (none of which have this issue
    (windows)) here's the ifconfig -a from the router.

    usbserial is not loaded. actually from reading the patch submission I
    suspected the official cause might be off... but I'm not kernel
    programmer all I know is where I could see the loss during tests.and I
    haven't been able to reproduce over dozens of reboots from this
    2.6.31.1-test-00091-gfa31221 kernel.

    I totally forgot to do it during the dump's so I hope these are still useful

    I haven't rebooted this in a few weeks (the router)
