Kernel memory corruption

Maybe, maybe not . . . .

There is a definite pattern here:
Code:

It looks like the kernel's internally generated messages have proper time stamps.
The messages sent into the kernel's buffer by the lab126 scripting certainly looks like it has problems. Almost as if they where using random numbers for the time stamps.

Groan -
I may have to set this little "corruption detection" project aside until I have enough time to read through whatever it is lab126 is doing with its message logging.
