I must correct myself on this issue: 3.18.24 did not fix it, but only hide it. 3.18.27 is affected as well. I'll try to find out what is causing it. Fortunately, the official 15.05.1 images seem to be unaffected (at least on the two devices I've seen the issue on, TL-WR841 v5 and v7), but building the CC HEAD will often yield broken images. There are multiple reports of this issue already, I've found the following: https://dev.openwrt.org/ticket/21773 https://dev.openwrt.org/ticket/21857 The issue is extremely suspectible to timing (or minor differences in the kernel image?), adding any additional debug output just made it go away in my tests so far... :/ Matthias
