Anything other than 0 means "tainted". The values are additive from this list....(may be out of date). 1 – A module with a non-GPL license has been loaded, this includes modules with no license. Set by modutils >= 2.4.9 and module-init-tools. 2 – A module was force loaded by insmod -f. Set by modutils >= 2.4.9 and module-init-tools. 4 – Unsafe SMP processors: SMP with CPUs not designed for SMP. 8 – A module was forcibly unloaded from the system by rmmod -f. 16 – A hardware machine check error occurred on the system. 32 – A bad page was discovered on the system. 64 – The user has asked that the system be marked “tainted”. This could be because they are running software that directly modifies the hardware, or for other reasons. 128 – The system has died. 256 – The ACPI DSDT has been overridden with one supplied by the user instead of using the one provided by the hardware. 512 – A kernel warning has occurred. 1024 – A module from drivers/staging was loaded. 268435456 – Unsupported hardware 536870912 – Technology Preview code was loaded -- A motto of mine is: When in doubt, try it out
