This error let me think, the memory (RAM) is unstable. Or any driver or
coLinux driver self changed the area of coLinux variables.

Try one of my ideas step by step:
Check the memory with memtest86.
Change the memory speed slower in bios settings.
Can you change the memory or CPU cache settings inside the bios? Try to
disable the cache.
Can you temporaly disable one core?
Diable the Online-Virus-Scanner, if you have.

How many RAM do you have? Have you shared memory for graphic card? Ones
heared from buggy graphic driver.

What is exactly the cpu model? "cat /proc/cpuinfo"
Ask Google for memory/chache problems on such cpu models.
