Hartmut,

I had a short test wit zram-swap these days and also saw this. 
I fixed this by changing the default compression-algo to lzo via etc/config/
system. My intention was not to use an additional kernel-module which will 
consume additional RAM which I just won by using zram ... (Indeed I did not 
check the numbers and only assumed)
