I have a D-Link DWA-140 USB Wi-Fi device which is rt2800 based (5392 chipset). I've been testing it on a BeagleBone Black running an Ubuntu 16.04 image (4.4.6 kernel).
(For the following, I am testing with a USB hub, because as I said in a previous e-mail, I get a kernel panic if I try to plug it in directly to the BeagleBone Black without the hub. However, I have also had this issue on a BeagleBone Black-based device running a 3.14.x Yocto-built kernel, where I was able to use it without a hub, and this issue also occurs when the device is plugged directly into the BeagleBone Black.)
If I plug in the rt2800 device, and wait for it to connect to an access point, then try to disable it by various methods, I get a kernel soft lockup.
Various methods to disable the device which cause the kernel soft lockup include (while current directory is e.g. /sys/bus/usb/devices/1-1.3):
echo 0 > authorized
echo -1 > bConfigurationValue
modprobe -r rt2800usb
echo 1-1.3 > driver/unbind
On the 4.4.6 kernel, they sometimes succeed, but often cause a soft lockup. On the 3.14.x Yocto-built kernel, I found they always fail if the Wi-Fi device is in-use (operating in client or access point mode) but succeed if it is idle.
E.g. in a recent test doing "echo 0 > authorized", I got the following in the serial debug console:
[ 172.167656] NMI watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [kworker/u2:0:6]
[ 200.167589] NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [kworker/u2:0:6]
[ 228.167550] NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [kworker/u2:0:6]
In this case, I was able to do a couple of successful "echo 0 > authorized" and then re-enable with "echo 1 > authorized", before the lockup occurred on a third "echo 0 > authorized". I'm attaching the corresponding dmesg dump.
