Subject: NETGEAR WG111v2 (USB RTL8187): freezes whole system when setup

I have an USB wireless card: Netgear WG111v2. It is reported in
syslog as:

    usb 4-2: Product: NETGEAR WG111v2
    usb 4-2: Manufacturer: NETGEAR WG111v2
    usb 4-2: SerialNumber: 000FB5D51ECA
    phy1: Selected rate control algorithm 'pid'
    phy1: hwaddr 00:0f:b5:d5:1e:ca, RTL8187vB (default) V1 + rtl8225
    usbcore: registered new interface driver rtl8187

On ifconfig up, the card always locks up two very different systems: a
relatively modern P4 desktop and P-MMX laptop with UHCI (ancient Compaq
Armada 1592DT) which has an OHCI.

The connection is not stable and sometimes the card just stops
talking to anything outside: the connection is not dropped, but
nothing works (no ping replies). Up/down interface does not help.

Aside from that there were no ill effects noticed.

I tried 2.6.27-rc7 and -rc8 with no difference.
