Since several bugs with much more details were merged into this one, the most likely early warning of zram problems are messages like
Buffer I/O error on device zram0, logical block 257912 [repeated X times] You get those right after modprobing / formatting zram. If you don't see those with the new kernel, either things are in good shape or the bugfix didn't work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1215513 Title: System locks up, requires hard reset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1215513/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
