Hi, I have seen a very similar issue as Andreas. It was found when streaming a mender file (using mender install <url> from my arm device. But I have also managed to reproduce a similar issue by flooding the interface using iperf. on target: $ sudo iperf -s -u On host: $ iperf -c <ip> -u -b 200M -t 300 Then it will almost instantly get problems causing the lm842 dongle to stop working. I'm using below fw: $ sudo dmesg | grep 8822c [ 19.282167] Bluetooth: hci0: RTL: loading rtl_bt/rtl8822cu_fw.bin [ 19.299025] Bluetooth: hci0: RTL: loading rtl_bt/rtl8822cu_config.bin [ 19.628570] rtw_8822cu 1-1:1.2: WOW Firmware version 9.9.4, H2C version 15 [ 19.641604] rtw_8822cu 1-1:1.2: Firmware version 9.9.15, H2C version 15 $ iperf -s -u ------------------------------------------------------------ Server listening on UDP port 5001 UDP buffer size: 176 KByte (default) ------------------------------------------------------------ [ 415.791320] rtw_8822cu 1-1:1.2: failed to get rx_queue, overflow [ 415.797443] rtw_8822cu 1-1:1.2: failed to get rx_queue, overflow [ 415.803511] rtw_8822cu 1-1:1.2: failed to get rx_queue, overflow [ 415.809635] rtw_8822cu 1-1:1.2: failed to get rx_queue, overflow [ 438.102270] rtw_8822cu 1-1:1.2: failed to get tx report from firmware [ 441.446726] rtw_8822cu 1-1:1.2: failed to send h2c command [ 471.480932] rtw_8822cu 1-1:1.2: firmware failed to report density after scan Any ideas what might be the cause of this? I have also tried to use the latest patch from Sascha that seems to be aimed to fix some issue I thought might have been related to this(https://lore.kernel.org/linux-wireless/20230404072508.578056-1-s.hauer@xxxxxxxxxxxxxx/T/#m54b7c8c604b91cfce470fcec8fc7d4c20f3056c9), but still get same behavior.
