Self modifying code in ARM 11 architectures

Hi All,
I am no success in booting up the ARM1176 processor with the linux-2.6.32
kernel.
While googling about the ARM Harvard architecture, I came to know that we
have to flush/invalidate the D-Cache and I-Cache
when using the self modifying codes.
So here my questions/doubts :
1) Is'nt it the kernel itself is self modifying code with lots of function
pointers ?
If yes, how is synchronization b/w d-cache and i-cache handled in the
kernel ?
2) Can this be the reason for the kernel not booting for me ?
Because If i disable the I-Cache in the config, then the kernel boots up
without any issues.
Any pointers on this will be of great help.
Thanks & Best Regards
Ashok
