Running the equivalent of the above command on my system does not result in a DMA error for my 14e4:4315 device. It runs for almost 22 minutes and then loses the connection with the following logged: Oct 19 10:13:06 linux-1fyl sshd[29903]: Accepted keyboard-interactive/pam for finger from 192.168.1.51 port 53026 ssh2 Oct 19 10:35:02 linux-1fyl kernel: [84171.492191] ieee80211 phy0: wlan0: No probe response from AP c0:3f:0e:be:2b:45 after 500ms, disconnecting.
