Hi, Basti already send a patch and it looks like it's just this
setting that causes problems:

CC15.05.1 on 1043nd:

root at openwrt:/tmp# cat /proc/meminfo
MemTotal:          28580 kB
MemFree:            9784 kB
MemAvailable:      15812 kB

current LEDE with vm.min_free_kbytes:

root at lede:~# cat /proc/meminfo
MemTotal:          27828 kB
MemFree:            9788 kB
MemAvailable:       7792 kB


current LEDE without the vm.min_free_kbytes setting:

root at lede:~# cat /proc/meminfo
MemTotal:          27828 kB
MemFree:            9996 kB
MemAvailable:      15636 kB


opkg, luci works fine on LEDE with 32mb devices again. This seems to
be culprit, the kernel size increase is only ~100kb and I guess
negligible.
