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....

[egreshko@meimei tainted]$ ./tainted
Taint value: 12289
[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
12    4096        An out-of-tree module has been loaded                          
13    8192        An unsigned module has been loaded in a kernel supporting
                  module signature
