--- Comment #1 from Nicholas Johnson (nicholas.johnson@outlook.com.au) --- On the first stack dump, it says not tainted, and then on the following ones, it says tainted. Can having a stack dump taint the kernel? Either way, I had not modified the kernel or loaded any out of tree modules, and it was not tainted until the error occurred.
