Bug 100280

/sys/... /card0 error

I just upgraded to the newest Ubuntu mainline kernel (see http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/, as of 2017-03-19) because of stability issues in 4.10.x. When hibernating and resuming, I got this in dmesg:

... which I am doing right now. After resuming, the system was unresponsive until I changed to the console (Ctrl-Alt-F1) and back to X (Alt-F7) and waited approximately 30 seconds, in which the screen was alternatively filled with frozen images of my desktop (but distorted), complete garbage (white noise) and nothing.

The kernel version is

Linux linuxkiste 4.11.0-999-generic #201703182201 SMP Sun Mar 19 02:03:00 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

The hardware is a MSI-7817 Intell Haswell i915 chipset integrated graphics, connected to a 22" Full HD Samsung S22C300 monitor via VGA.
