Posts #51 and #53 are wrong: this bug is NOT FIXED in either 3.2.0-54.82
or 3.8.0-31.46 from the 12.04 (precise) repositories. There might be
something fixed about zram in there (as suggested by the changelog), but
the last sector of /dev/zram0 is still bad (as reported in #43), and
this will lead
For 1a, also uninstall zram-config if present.

System locks up, requires hard reset

IMO, this bug *is* a duplicate of #1215513. The real problem is that the
zram kernel module creates a block device with a bad sector at the end.
When you try to swap on it, anything can happen, from system lockdowns
to program crashes to nothing (e.g., if you have so much RAM you never
get to use
I stand corrected - maybe. I wrote a program that allocates, sets, and
moves around more memory than my RAM. I added the zram0 as a swap, with
the bad sector included ('mkswap' without '-c'), and with higher
priority than the disk swap. I ran the program once only, because it
takes half an hour
