Dan,
My "issue" is with an old, but "supposedly supported" LTS release,
12.0.4 Server. SINCE it's a Server release, it "assumes" I know what
I'm doing (even to only setting up in Text mode, and "letting" me only
"apt-get install" what I ACTUALLY need to install, which means a working
X Server and FVWM. (Be honest, folks! How many of you have run that in
the last decade? LOL!)
My situation is different than yours, as I'm running a late, "security
fix" for Kernel 3.2. As such, there IS NO software, to run zram0, just
some sort of boot code, probably in the Kernel. So /dev/zram0 was "sort
of" set up, as it was "defined", but not configured. So bug #1217189
MUST be re-opened, for the older Kernels, and because it adversely
affects a LTS release!
I posted a message on 1217189, but here is a capsule summary:
/dev/zram0 is set up, so I can do fdisk on it, but no partitions exist,
because the bootup code is following MY instructions to only use the
Disk SWAP I defined for it. HOWEVER, since the messages come up, it's
defined, so the actual RAM to run the server is less. So, what I
encountered, when I rebooted it (when I was able to get Stand-alone time
on it), let the messages come up, bring up FVWM and some of my heavy
resource programs, such as Hercules (IBM Mainframe emulator) and Turnkey
MVS, which runs an older, "public domain" (even if IBM doesn't like it,
they must "abide by it", because there is no copyright code, like there
is in, say, MVS/ESA or z/OS, the heavily protected releases).
My experience was heavy use of the Disk SWAP partition, to the level of
Thrashing. So, while these Emulators were running (but slowly), I went
into Root (which I do, as a Linux Administrator, even though Ubuntu
"frowns on it" and "prefers Sudo"! LOL!) And then, I brought down
zram0, using instructions, earlier in this forum. GUESS WHAT? It went
back to normal, with all RAM access being IN THE RAM, rather than in
SWAP. This test went SO FAST, I was able to reboot again, and go back
into production, with two hours to spare. [Pat on back. "At-a-boy",
but no raise]. :-)
So, if zram0 is coming up, with the messages, but your systems are not
freezing, you may still be getting Performance Hits, instead of only
"ugly error messages".
I repeat: Please re-open #1217189, for older kernels, which are getting
ZRAM kernel code, even if not trying to define the RamDisks.
Thank you and best regards,
Kenneth Parker, Seattle, WA

Bug description:
Since I started using 3.8.0-29 I experienced system lock ups at random
times. First one was while running Virtualbox (windows guest) but
later have been without virtualbox running for example while shutting
down or while reading a webpage.
I could not find any relevant log, but I'd post any log file
considered useful.
This has hapened in 2 different machines (the one im reporting from is
intel with intel graphics and the other is AMD with radeon graphics).
Both 64 bits.
Up until 3.8.0-27 inclusive I had not had a lockup in years in any of
those machines. I have been running Ubuntu 64 bit since at least 2008
in one of them.
