I've failed to state. This readings are *after* crash. The system is
more or less usable, if all apps are restarted. The desktop is broken
and mouse pointer fixed, but the rest can be fixed. However, swap has
been actually disabled via 'vm.swappiness=0'. I've reenabled it to see
if it helps.

I could recompile intel video driver or some another part of X with
debug logging, if it helps to confirm or reject the OOM hypothesis. I
would just need a patch.

Is it OK to note here?
