  1. I recently rebooted my Cubietruck after a longer time because the WiFi daemon didn't work properly anymore. After the reboot, however, the system didn't boot from NAND anymore. I attached a serial console and got the following kernel panic (the full serial log is attached): <0>Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance. [ 12.867986] Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

I'm using the legacy kernel 3.4.113-sun7i. Recreating the kernel image using mkimage didn't help. What could I do now? serial.log
  2. I've set up a HE.net IPv6 tunnel on my CubieTruck, which announces itself in the network as a router for IPv6 network traffic. However, when I transfer data from other computers via the CubieTruck, bandwidth is very bad. rsyslogd causes a very high load on the CubieTruck and transfer rates are only up to several hundred KB/s. However, when I test downloading files from the CubieTruck itself, load doesn't increase and I can use my full line speed of 4 MB/s. As rsyslogd is the logging daemon, I looked into the syslog and found hundreds of page allocation failures like the one I attached to this post. What's wrong and how can I fix this? exception.txt
