Issue/Introduction

Tainted kernelsĀ In kernel crash-dumps, or even in routine log messages, one may see references to a kernel being "tainted".

Resolution

This is not any sort of error condition and is entirely normal in the Crossbeam environment.

It may be seen in such routine log messages as:

 Nov  3 16:01:36 sean1 kernel: cbshb: no version for "cbs_eeprom_get_chassis_type" found: kernel tainted. 


To confirm the level of tainting in a Crosbeam kernel, one can perform:

     cat /proc/sys/kernel/tainted


The typical value returned will be '3', indicating that the kernel is tainted in two manners (3 => 1 || 2):

- The '1' element indicates that a non-GPL kernel module has been loaded into this kernel.
- The '2' part suggests that a kernel module was force-loaded.

These are entirely normal and expected.
