And, FWIW, here are the meanings for the various bits....
[egreshko@meimei tainted]$ ./tainted -i
[bit] [bit value] [description]
0 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
1 2 A module was force loaded by insmod -f
2 4 Unsafe SMP processors: SMP with CPUs not designed for SMP
3 8 A module was forcibly unloaded from the system by rmmod -f
4 16 A hardware machine check error occurred on the system
5 32 A bad page was discovered on the system
6 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
7 128 The system has died
8 256 The ACPI DSDT has been overridden with one supplied by the
user instead of using the one provided by the hardware
9 512 A kernel warning has occurred
10 1024 A module from drivers/staging was loaded
11 2048 The system is working around a severe firmware bug
12 4096 An out-of-tree module has been loaded
13 8192 An unsigned module has been loaded in a kernel supporting
module signature
14 16384 A soft lockup has previously occurred on the system
15 32768 The kernel has been live patched
For 12289 that works out to be....
