I have exactly the same problem. All is well until I try to
write to the shared memory. The error message always states
the address with a 0xc..... prefix, as does yours.
If the shared area starts at 0x1f00000 and I try to write to
the first byte the kernel error complains about 0xc1f00000.
Any help is appreciated!
Jim.
