Hello Thorsten,

after writing the mail to Rafael Thomas provided the idea on irc to test
using

	intel_idle.max_cstate=2

(or =1 or =0) on the kernel command line given that the splat hints at
this happening for C3.

Can you please add this (with =2) to your bootloader and if the problem
happens again, tell us here and reduce the number further?

Best regards
Uwe
