@chiluk: For me discard option in fstab was causing the problems and I
did full secure erase. Even twice, after I couldn't boot because of
mentioned errors.

Amazing, I've encountered those issues on regular use, without TRIM enabled.
At least it's what I think because I had to force - shutdown the laptop.
I guess this is it for me.

But from what I know NCQ is important to maintain SSD performance... did
you test it in both cases?

Title:
trim does not work with Samsung 840 E
I moved from kernel 3.19.3 to 4.0.1 and the problem is still there.
There were no issues on previous firmware.
Looks like TRIM simply doesn't work on EVO now.
It not a valid Ubuntu bug, maybe they can fix it in kernel somehow, but maybe
it's just time for a new drive...

There is some interesting commit about TRIM for EVO 850 in kernel:
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-4.0.y&id=6fc4d97a4987c5d247655a157a9377996626221a
And some other drives as well:

Same here and as addition to the image with errors above I've attached some
other errors I actually captured.
In my case, I had to disable discard command in /etc/fstab because system
wasn't able to boot anymore.

Title:
bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu1: bcmwl kerne
Mouse: a4tech X-710F, double clicks started few days after fresh install of
kubuntu 11.10
I couldn't find the solution, so I checked the mouse on 2 previous kubuntu
releases where it used to work just fine - the bug was there too.
Finally I assumed this can be a hardware problem so I've desolder
