A simple workaround is to blacklist the zram module, and update your initramfs:
1. create a text file /etc/modprobe.d/blacklist-zram.conf: blacklist zram 2. enter command update-initramfs -c -k all After reboot, the zram module will not be loaded anymore. You can also temporarily unload the module: 1. list swap devices: swapon -s - it should produce output similar to: Filename Type Size Used Priority /dev/zram0 partition 4102348 55052 100 /dev/sda9 partition 4112604 0 -1 2. now turn off swapping on zram0: sudo swapoff /dev/zram0 3. now that module is not used anymore, it can be unloaded: sudo rmmod zram -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1217189 Title: Buffer I/O error on device zram0 (possibly causing complete machine lockup) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1217189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
