Yeah small problem. They even make it difficult to figure out if it's an OPAL 
variety of SED. If it is, it's always encrypting, it's just unlocked by 
default. So figuring out a better way to support SEDs is useful.

 As for discard, can I just add this after defaults?

defaults is just a place holder, you can change defaults to discard.

Have you had about 19 of these freezes? You said you've had the problem with 
lock screen which implies inactivity. I wonder if the system is 
sleeping/hibernating and the drive isn't waking up in time and dbus or gdm or 
gnome-shell are getting irritated. I'd ssh in remotely, run journalctl --follow 
and see what's displayed the next time you have a freeze.

An update;

  I reinstalled on the Samsung 840 Pro not long before I ran/reported 
the smart test earlier in the thread. I've been running now for a couple 
days with F18 and have not had another crash. The main differences from 
last time is that;


a) I had installed windows on the drive and ran the Samsung SSD utils, 
though I don't think it changed anything unless it did so behind the scenes.


b) I 0'ed out the entire drive (over USB from F18 on my older SSD) 
before reinstalling F18 on the Samsung.


  Not sure how or if these could have changed anything. However, this 
is the longest stretch I've gone without a crash since getting this 
Samsung drive.

FYI this isn't a good idea with SSDs. Use ATA Secure Erase instead with hdparm, 
or the included Windows utility can do this - it almost always requires a 
direct SATA connection because most of the USB to SATA bridge chipsets are crap 
and don't pass through these ATA commands.

What mount options are you using? In particular do you have discard enabled?

 Thanks for the tips on secure erase. I'll use that in the future.

I would do it now because as far as that SSD is concerned, every single block 
is in use, and then also you should be using the discard mount option, and also 
not using dmcrypt. The 840 Pro supports FDE, that's what you should use. But 
for reference dmcrypt supports TRIM passthrough, just not by default.

Thanks for the link and key word!

I've started to lose count, but I think it's been 12 or 13 lock ups. 
However, one of those failed to recover or instantly re-failed after 
restarting dbus. At least, this is how many I noticed. Does the number 
19 come from:


=
0x0009  2   19  Transition from drive PhyRdy to drive PhyNRdy
0x000a  2   19  Device-to-host register FISes sent due to a COMRESET
=

If so, is this a sign of a bad drive? If so, could gnome/dbus/whatever 
handle the failure better?


I just reinstalled on the Samsung last night. As soon as I get a crash, 
I will run 'journalctl --follow' and 'dmesg' and report whatever is shown.


Thanks again!

Frequent dbus(?) crashes with Samsung 840 Pro SSD

2013-02-18 Thread Digimer
Last weekend, I both a new Samsung 840 Pro 256GB SSD. Prior to this, I 
was using a Corsair Performance Pro 256 SSD without issue (F17 had been 
upgrade to F18 about a week before). I got the drive to do a fresh install.


From last weekend until Saturday, I would get ~2~3 hard crashes a day. 
Gnome 3 would lock up hard, but I could ctrl+alt+fX to get to other 
terminals. Here's my original post/thread;


http://lists.fedoraproject.org/pipermail/users/2013-February/430993.html

Two days ago, I reinstalled F18 on my Corsair drive. I had the Samsung 
connected as a USB drive to restore my files and after a few hours, the 
system locked up again ('tail -n 100' below). I pulled the Samsung out 
of the laptop and booted with just the Corsair and it's been rock solid 
since.


Each time it crashed, it *looked* like a dbus hang-up. However, I am not 
a programmer so I could be way off base with this guess. Here's the last 
log from the system after the last crash (when the drive was the OS 
drive, I didn't get the messages from the crash when it was connected 
via USB);

I assume you've looked at smartctl -a on this drive, and that's why you don't 
think it's just a bad SSD that needs to be swapped out for replacement? I'm 
using an 830, which is related to the 840, but admittedly different in some 
important ways; but I'm not experiencing problems like you're describing.

And what have you found in dmesg for the time this is happening? Or 'journalctl 
--follow' using ssh?

Why do you say this? There's nothing in your syslog that implicates dbus, or 
anything else for that matter. I also think that's the wrong diagnostic tool 
for this, actually.

I went so far as to install Windows 7 on the 840 Pro, downloaded and ran 
Samsung's own tool to verify it was at the latest firmware and was 
healthy. The smartctl is below.


Next time it crashes, I will check dmesg and run that command.

If it's not dbus, which I readily admitted it might not be :), I would 
love to hear suggestions. The reason I thought it was related to dbus 
was that I kept seeing so many dbus messages at the time of each crash. 
Also, restarting the dbus.service would (all but one time) recover Gnome 
and restore the system to working. Of course, that could be normal and 
unrelated.


Again, I am open to advice or suggestions.

Have you had about 19 of these freezes? You said you've had the problem with 
lock screen which implies inactivity. I wonder if the system is 
sleeping/hibernating and the drive isn't waking up in time and dbus or gdm or 
gnome-shell are getting irritated. I'd ssh in remotely, run journalctl --follow 
and see what's displayed the next time you have a freeze.
