freezes are instant, without any sluggish or strange mouse or keyboard
behavior, and the system locks completely, including low-level functions
such as Ethernet pings. I'm also not using an Nvidia card, nor any
proprietary driver,
I believe I had the same issue, my M91p would freeze after some random time
from boot, however its not an immediate hang, the mouse cursor goes on a go
slow, then disappears over a few seconds, keyboard and mouse are then totally
unresponsive including ctrl-alt-f1 etc. However I *think* its

Daniel Arnitz, could you please test the latest upstream kernel available

allow additional upstream developers to examine the issue. Once you've tested
the upstream kernel, please comment on which kernel version
I have the same issue. I reported this in another bug report

Same story here. I tried everything between 12.04 and 14.04, freezing
the system randomly. Latest bios upgrade, switching memory banks or
disks seems to have nothing to do with the problem. It appears that the
last stable distro was 11.10 in 14 out of 15 M91p we have left.

Thank you! I have not yet tried the Saucy kernel. I'm running into
https://bugs.launchpad.net/ubuntu/+source/xorg-lts-saucy/+bug/1268463 ,
so this will likely not be a smooth update. I can't risk breaking this
system right now, but I will make the update ASAP. Thank you!

Daniel Arnitz, thanks for the remote capture. However, no crashing that
I saw. I'll mark Confirmed for now so someone else may review. Have you
