Catfriend1:

Supply the following if possible:

  • Device problem occurs on
    Archer C7v2

  • Software versions of OpenWrt/LEDE release, packages, etc.
    OpenWrt 19.07-rc.2

  • Steps to reproduce
    Today worked on batman-adv via ad-hoc between two devices. Device A has LAN to bat0, batman-adv works over ad-hoc wifi, Device B has bat0 to LAN. (Device B has only one wired client behind)
    Both devices (Archer C7v2 with OpenWrt 19.07-rc.2) had multiple crashes of the below printed type resulting in only 10 MBit/s download speed on the computer attached via LAN to Device B. Before the kernel.warn log line appeared on one of the APs, the speed was full 100 MBit/s. As soon I reboot the "kernel.warn"ing AP, the speed is 100 MBit again. bat0 is bridged to eth0.101 on both ends.
