Mel, the reason I do NOT believe this is a duplicate of # 1215513 is that many get error messages (including I/O errors in some cases) WITHOUT a hang. But any time I see I/O error on any disk, whether "hardware, ram or simulated [i.e. network]", there's a chance of data corruption, even without crashes. Please reconsider.
Steve, you also mention I/O error messages. Once again, that could corrupt data, the WORST TYPE of error, in my NOT SO humble opinion. (Think about it: If SWAP data comes back in, and your "bank balance" changes from 5000 to 500,000, you might THINK you have more in your account than you do, causing "mishaps" in International Finance. [Example used, due to how badly your life could be hurt]. My personal solution is to come up with ONLY a Root Text console [yes, Ubuntu users aren't SUPPOSED to become "real Root", but I've been doing this sort of thing since the 1990's], "rmmod zram" [with prejudice, if possible], and I'm prepared to do a "permanent rename" of the correct name of the module, as soon as I "get around" to it. [Visions of Round Tuits...] A point I made earlier: Even if a SWAP partition is NOT made out of /dev/zram0, part of RAM is being "reserved for nothing".
