Hello,

zram shows an error when mounting a swap partition,
current version Linux kernel 3.10.6,
previous versions worked, I suppose that latest zram patches have some 
problem,

machine is an AMD64 dual core, 4GB RAM

+ modprobe -qb zram num_devices=2
+ echo 104857600 > /sys/block/zram0/disksize

# mkswap /dev/zram0
Setting up swapspace version 1, size = 102396 KiB
no label, UUID=6c249930-2ba0-46cf-a8c6-766481942b7d

# pager /var/log/dmesg 
(no more errors shown)

# swapon /dev/zram0

# pager /var/log/dmesg 
...
