This kernel seems to fix both this bug and
https://bugs.launchpad.net/bugs/505271

Unfortunately when I open the lid I still see the display notification:
"could not switch the monitor configuration / could not set the
configuration for CRTC 64"
and it feels that the PC is unresponsive for 4-5 seconds (slow keyboard input)

this is the output of dmesg:
