Here is what I found with at76-usb as it is in the current kernel:
static int at76_wait_completion(struct at76_priv *priv, int cmd)
{
int status = 0;
unsigned long timeout = jiffies + CMD_COMPLETION_TIMEOUT;
do {
This can go wrong in a preemptible kernel. You have no guarantee the full
timeout is granted.
@@ -1631,7 +1633,7 @@ static void at76_rx_tasklet(unsigned long param)
buf = (struct at76_rx_buffer *)priv->rx_skb->data;
if (urb->status != 0) {
- if (urb->status != -ENOENT && urb->status != -ECONNRESET)
+ if (urb->status != -ENOENT && urb->status != -ECONNRESET && urb->status != -ESHUTDOWN)
Should also check for ESHUTDOWN, also in at76_mac80211_tx_callback()
