I thought dpkg --purge zram-config as well as commenting any reference out of /etc/rc.local would do the trick, but the module (and its ominous dmesg warnings Buffer I/O error on device zram0, logical block 257912) keeps getting loaded. I've grepped /etc/init and /etc/init.d for zram and there were no matches. I've error on device even redefined mkswap to log how it was called (because the "buffer errors" occur when mkswap touches protected memory) -- amazingly I didn't get any calls. So I can't figure out what configures zram (calling mkswap + swapon). I've taken to breaking the zram.ko to stop its loading. But I would still like to figure out what specific init script loads it. Any ideas? Note that I'm looking for answers about how to track down which init or startup script configures zram -- I know very well that the bug might already be fixed, that you can disable zram in several ways etc, and such answers would be off-topic. 12.04 administration init.d share|improve this question edited Sep 17 '13 at 7:04 Kevin Bowen 10.4k104758 asked Sep 17 '13 at 6:11 dan3 2142310 zRam is integrated into the kernel as of version 3.2 so I expect there not to be a startup service. Now if you installed the zram configuration tools manually (as described here: webupd8.org/2011/10/increased-performance-in-linux-with.html ) the service would be /etc/init.d/zramswap but that is not default. –Rinzwind Sep 17 '13 at 7:10 mkswap and swapon /dev/zram0 are integrated in the kernel? I didn't know that was possible... –dan3 Sep 17 '13 at 7:15 Sure, but modprobing zram doesn't imply setting up zram. What
