Unable to handle kernel paging request at 00000000b1b06636

I create a ramfs during boot and map the file to all process (during process creation) at same address range to facilitate zero copy during IPC. I do see address range mapped to all processes.

root@ cat /proc/2285/maps

0804d000-080b4000 rw-p 0804d000 00:00 0 [heap] 9bef8000-b93b8000 rw-s 00000000 00:08 498 /icmmem (deleted)

I dont know about what you are trying to do, but all this error says is that you have a pointer to something that does not exist in the kernel memory table.
