    Subject2.6.25-rc2 regression in rt61pci wireless driver

    Firstly, please cc me into any any replies - I'm not subscribed.

    In 2.6.25 kernels, my wireless LAN dies after even the smallest amount
    of network activity. The following screen cut shows what I typically

    [chris:~]$ uname -a

    As you can see, after a few packets, the ping application hangs and
    after that point, all network accesses fail. There are no error
    messages written to the logs when the network dies. I can restart the
    network by simply unloading and reloading the driver. This hang does
    not occur with a different wireless card that uses the rtl8180 driver.

    My config and the output from dmesg (after reloading the driver) are
    attached. I have Ralink debugfs enabled so can provide any additional
    diagnostics that may be helpful from that source.

    (I should perhaps add that I am sure that this is not the same problem
    I reported tthrough bugzilla (bug 9860) a few weeks ago, which it
    seems was a problem with my AP/router. Since resetting my AP/Router, I
    can reboot to and the wireless network works reliably with
    the same hardware.)

    The hardware is a Belkin F5D7010 802.11g Notebook card communicating
    with a Draytek Vigor 2600 802.11b combined AP/Router/Broadband Modem.

    I will be more than happy to provide additional diagnostics, but
    please bear in mind that I am not a git user, so cannot do bisects. I
    am, however, perfectly capable of applying or reverting patches,
    rebuilding and re-testing, so I am quite happy to do that.

    Thanks in advance.
