Do you mean you don't care about the state of the file system after a reboot? Do you rebuild it from scratch each time on restart? Even so, bcache was designed around SSD media behavior, there are some notions non-applicable to zram drives, like buckets. They might introduce some inefficiencies, but should not affect the semantics. Could show the errors you receive. Also, could it be zram-related? Did you try RAM block devices instead? What IO scheduler do you use on zram? Could you try noop and see what happens?
