[Dan Muresan <1215513@xxxxxxxxxxxxxxxxxx>]

I've tested 3.8.0-31-generic (linux-image-3.8.0-31-generic =
3.8.0-31.46~precise1). To the admins: when asking us to test "the latest
in -proposed", please tell us which package and which version. It makes
it easier to interpret the record in the future, when the "latest in
proposed" may be different (or when your proposed solution has been
removed / replaced)

I'm using the following test now:

echo '4096 * 4096' | bc -l > /sys/block/zram0/disksize
mkfs.ext2 /dev/zram0

And I get this with dmesg -T:

[Sun Sep 22 23:05:40 2013] Buffer I/O error on device zram0, logical block 4095
[Sun Sep 22 23:05:40 2013] lost page write due to I/O error on zram0
[Sun Sep 22 23:05:40 2013] Buffer I/O error on device zram0, logical block 4095

I don't think this is a good kernel. In the terminology of
https://lkml.org/lkml/2013/8/13/22, both [1] and [2] should be in the
kernel, so that both bug A and bug B are fixed.

I'll check how to find the changelog for a kernel and whether the other
-proposed (3.2, 3.5) kernels also have the same problem.

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.
