Comment 10 for bug 1556965

Alas, the new kernel (linux-image-4.5.0-040500-generic) exhibits another even more catastrophic behaviour!

Now the kernel crashes completely, the screen is black and now the host appears to be completely dead (no ping response, no keyboard response). Upon restart the only indication I can find is a series of ASCII NULLs in kern.log and Xorg.0.log. This problem seems to occur more seldom than the first one (every few days, as opposed to several times a day), but this also seems to be related to screensaver/power saving. I observe the problem when returning to the machine after being away for a while.

This is really strange, this machine was very stable running 14.04.

Anyway, I guess this could be an unrelated bug, so I guess it is time for yet another bug report...

As far as I am concerned, this bug can be closed.
