Hi Petko, I'm testing a USB to ethernet adapter with Greg's usb-linus branch (based on 3.9-rc4). I'm seeing an odd behavior, and I'm suspicious that a second behavior found by Stephen Hemminger may also be related: http://marc.info/?l=linux-usb&m=136364625519235&w=2 When I load the pegasus driver for this adapter (without an ethernet cable hooked to it), and this is on a cold system boot or a complete unloading and reloading of the usbcore, I get the following warning:
Unfortunately the machine i ran my tests on does not have xHCI nor i used Greg's tree. I did not observe this warning on both 3.8.4 and Linus' 3.9-rc4. It looks like to me that the issue is outside the driver code.
However, i am curious whether you experience the same problem with other (non-ADMtek based) usb-to-lan adapters which support xxx_set_multicast(). These calls are asynchronous by nature and should also trigger this warning. Please let me know if this is not the case so i start digging into pegasus.c.
