Thank you for the hint. At 624 MHz I still get the kernel panic, with and without bnep. kernel-panic-11-624MHz-no_bnep.txt

I have now blacklisted the bnep module: ksoftirqd uses less CPU, IP forwarding is a bit slower, but the kernel panic still occurs after a while.

Hi, we have found an issue with Armbian 5.31 on a Banana Pi M2+ board that occurs when IP forwarding is enabled and there is high network load. How to reproduce this issue: Enable IP forwarding on the M2+: sysctl -w net.ipv4.ip_forward=1 Install nginx or another web server on the M2+ Use ncat to send a large file (e.g. 4 GB) from one host to another via the M2+ Use ab to create additional load on the nginx server Soon there will be a kernel panic, for example (see attachment for more examples): Before the kernel panic the ksoftirqd thread uses 100% of one core.

Hi, after the update from Armbian 5.23 to 5.25 on a Banana Pi M2+ board, the MAC address and CPU serial number have changed. This can be reproduced by just updating the u-boot package on Armbian 5.23: # ifconfig | grep HWaddr eth0 Link encap:Ethernet HWaddr da:c7:a0:49:24:d6 # grep Serial /proc/cpuinfo Serial : 2435501d0a0e4800004d # dpkg -i linux-u-boot-bananapim2plus_5.25_armhf.deb # reboot # ifconfig | grep HWaddr eth0 Link encap:Ethernet HWaddr 3a:89:a1:23:98:a6 # grep Serial /proc/cpuinfo Serial : 24005035871c481d0a0e Does anyone know the reason for this? Did u-boot change the way these numbers are generated? Best regards
