0 G/P 1 proprietary module was loaded
1 _/F 2 module was force loaded
- 2 _/S 4 SMP kernel oops on an officially SMP incapable processor
+ 2 _/S 4 kernel running on an out of specification system
3 _/R 8 module was force unloaded
4 _/M 16 processor reported a Machine Check Exception (MCE)
5 _/B 32 bad page referenced or some unexpected page flags
1) ``F`` if any module was force loaded by ``insmod -f``, ``' '`` if all
modules were loaded normally.
- 2) ``S`` if the oops occurred on an SMP kernel running on hardware that
- hasn't been certified as safe to run multiprocessor.
- Currently this occurs only on various Athlons that are not
- SMP capable.
+ 2) ``S`` if the kernel is running on a processor or system that is out of
+ specification: hardware has been put into an unsupported configuration,
+ therefore proper execution cannot be guaranteed.
+ Kernel will be tainted if, for example:
+
+ - on x86: PAE is forced through forcepae on intel CPUs (such as Pentium M)
+ which do not report PAE but may have a functional implementation, an SMP
+ kernel is running on non officially capable SMP Athlon CPUs, MSRs are
+ being poked at from userspace.
+ - on arm: kernel running on certain CPUs (such as Keystone 2) without
+ having certain kernel features enabled.
+ - on arm64: there are mismatched hardware features between CPUs, the
+ bootloader has booted CPUs in different modes.
+ - certain drivers are being used on non supported architectures (such as
+ scsi/snic on something else than x86_64, scsi/ips on non
+ x86/x86_64/itanium, have broken firmware settings for the
+ irqchip/irq-gic on arm64 ...).
3) ``R`` if a module was force unloaded by ``rmmod -f``, ``' '`` if all
modules were unloaded normally.
