I just wrote an Email to the manufacturer of my "TUXEDO InfinityBook
Pro 13" and referenced this bug report. They sell specifically Linux
suited Hardware. Since they offer a Distro of their own I hope they can
shed some light on the hardware issues raised here. If there are some
special kernel parameters to be set they should know about it.
Also, I tried to provoke the system freeze with a memory bomb:

I tried this on AC and on Battery to no avail I'm afraid. After some
sluggish input behaviour the system kills the process, as it should.
Maybe I need to consume the memory of the graphic chip? For Intel HD
Graphics, is that even a separate thing?
