bittorf:
Supply the following if possible:
with e.g. r2805 on a 'TP-LINK TL-WR1043ND' sometimes i can see:
# top Mem: 24448K used, 3492K free, 5468K shrd, 448K buff, 6512K cached CPU: 0% usr 100% sys 0% nic 0% idle 0% io 0% irq 0% sirq Load average: 8.80 8.48 7.93 6/48 7243 [...] no task >10%see the "100% sys" - sometimes load goes >25.

sometimes it goes away without doing anything.
wifi-mode is adhoc+ap - see the config:
