When you said "more aggressive timing settings", what were you referring to?

No motion timing or step timing should have any real effect on Linux
if you are using hardware stepgens

Ok, yes i use hardware stepgens. So i think the problem has to do with linuxcnc 2.7, because i have never had this problem before with 2.6 :/

Just guessing but it looks more kernel/low level servo thread related rather than LinuxCNC version related

What servo thread rate are you using?

Have a look at the top of the attached picture, it clearly says it could not handle a paging request, and is always a sign of failing memory, it has the address of the memory it failed to write or read.
