Intel Graphics on HP Elitebook Folio 1040 i5 5200U

I have tried to get Arch Linux to run on a HP Elitebook Folio 1040 with an i5-5200, with mixed success. Currently I'm struggling with the Intel integrated graphics, which gets listed by lspci as

VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)

I have installed xf86-video-intel as well as the libva drivers, and my kde plasma desktop with sddm runs satisfactorily so far (apart from some tearing when scrolling web sites and the like). However, when I switch to another tty from the Xserver or if I manually stop the xserver so the machine falls back to tty, I get very weird graphical errors that look like the entire screen moving to the left at high speed and coming back in from the right continuously, producing partly overlapping display of the shell output while flickering like a maniac. When I switch back to X with <Ctrl><Alt><F1>, it MAY work, however it very often starts off with the screen moving to the left with decreasing speed and eventually halting after 1 or 2 seconds so it's usable again. Some times though it doesn't stop moving or even getting so fast that I can't see anything anymore. The underlying system is working though, I can issue shell commands and the like.

If I start without X, the shell is working nicely until I start X once.

If anyone needs any further information, just ask. I couldn't find anything in the Xorg.0.log that I would consider to be of interest. When switching to and from tty, this gets logged there:

[  2070.956] (II) AIGLX: Suspending AIGLX clients for VT switch
[  2071.567] (II) AIGLX: Resuming AIGLX clients after VT switch
[  2071.567] (II) intel(0): switch to mode 1920x1080@60.0 on eDP1 using pipe 0, position (0, 0), rotation normal, reflection none
[  2071.582] (--) synaptics: SynPS/2 Synaptics TouchPad: touchpad found

Also, the intel integrated audio doesn't seem to work, but that's another story.

It's a bug with the Intel Driver in recent versions (Kernel 4.0+).

Workaround is to add

i915.enable_ips=0

to your kernel cmdline/kernel parameters.
