(Get the code!)
Hi Martin,
True, I cannot switch between tty's. The whole system is unresponsive to any keyboard commands.
About SysRQ (reisub): I cannot try it, because in my keyboard (Logitech K740) there is no SysRQ button.
Usually it is the "alt-function" of the PrintScreen button, but not here.
About the kernels. I have seen this hanging behaviour with the Ubuntu kernels 3.16.0-23 and 3.16.0-24 (the latest).
But always with "quiet" in the kernel booting line.
If I remove "quiet" and turn to verbose mode, the booting will significantly slow down (because of the rolling text lines in the screen), but I haven't seen these hangs then.
In the log files, there is nothing, no errors about this.
Only one in x.log pointing that vesa module is not present. But I do not have vesa driver installed, instead I have modesetting and fbdev installed. They are loaded fine. And of course the Intel driver, the loading of which always succeeds.
