Log Message

Print out a little more info about the kernel version when things crash.
Now things look like:

ADSP-BF537-0.2(Detected 0.3) 500(MHz CCLK) 125(MHz SCLK) (mpu off)
Linux version 2.6.28.10-ADI-2009R1-pre-svn6445
Built with gcc version 4.3.3 (ADI-trunk/svn-3383)

Which will help alot when tracking down issues for users.
