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