OK, I've found the problem: 1. it does work with init=/bin/bash 2. it did not work after doing a binary search in the modules, even removing all modules did not help 3. I figured out that it only happens when I update the CPU's microcode, (booting with init=/bin/bash and /etc/init.d/microcode.ctl start triggers it) Even better: s2ram always gave me my display back when s2ram under console. Now I wonder if this is Bug #12100 ? Unfortunately I need the microcode update, as I am suffering from a) PAT WC disabled due to known CPU erratum. b) coretemp coretemp.0: Errata AE18 not fixed, update BIOS or microcode of the CPU! Anyway I now have a chance to test whether #11698 still occurs. Soeren
