Hi, commit bfe9b9d2d introduced a workaround for link status detection. That workaround seems to cause a tight loop of usbnet_cdc_status being called all the time, which in turn prints "kevent 11 may have been dropped" in the kernel log all the time.
I am not sure about the semantics, i just found the commit causing the problem and a workaround for my device. For me just removing the workaround block works, so does inserting a break so usbnet_link_change does not get called twice. But with the break ethtool wont report a link anymore. I am guessing that calling usbnet_link_change twice in a row (off and then on) will trigger an event that ends up on the very same codepath. The problem is already described in several bugtrackers: https://bugzilla.kernel.org/show_bug.cgi?id=185641 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1626371 https://bugzilla.redhat.com/show_bug.cgi?id=1383810 My device is a "13b1:0041 Linksys". regards, Henning -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
