tainted:
tainted
Non-zero if the kernel has been tainted. Numeric values, which can be
ORed together. The letters are seen in "Tainted" line of Oops reports.
1 (P): 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 (F): A module was force loaded by insmod -f.
Set by modutils >= 2.4.9 and module-init-tools.
4 (S): Unsafe SMP processors: SMP with CPUs not designed for SMP.
8 (R): A module was forcibly unloaded from the system by rmmod -f.
16 (M): A hardware machine check error occurred on the system.
32 (B): A bad page was discovered on the system.
64 (U): 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 (D): The system has died.
256 (A): The ACPI DSDT has been overridden with one supplied by the user
instead of using the one provided by the hardware.
512 (W): A kernel warning has occurred.
1024 (C): A module from drivers/staging was loaded.
2048 (I): The system is working around a severe firmware bug.
4096 (O): An out-of-tree module has been loaded.
8192 (E): An unsigned module has been loaded in a kernel supporting module
signature.
16384 (L): A soft lockup has previously occurred on the system.
32768 (K): The kernel has been live patched.
65536 (X): Auxiliary taint, defined and used by for distros.
131072 (T): The kernel was built with the struct randomization plugin.
1 (P): proprietary module was loaded
2 (F): module was force loaded
4 (S): SMP kernel oops on an officially SMP incapable processor
8 (R): module was force unloaded
16 (M): processor reported a Machine Check Exception (MCE)
32 (B): bad page referenced or some unexpected page flags
64 (U): taint requested by userspace application
128 (D): kernel died recently, i.e. there was an OOPS or BUG
256 (A): an ACPI table was overridden by user
512 (W): kernel issued warning
1024 (C): staging driver was loaded
2048 (I): workaround for bug in platform firmware applied
4096 (O): externally-built ("out-of-tree") module was loaded
8192 (E): unsigned module was loaded
16384 (L): soft lockup occurred
32768 (K): kernel has been live patched
