i am faceing a problem while running Linux kernel-188.8.131.52 after some time.the error is Unable to handle kernel NULL pointer dereference at virtual address 00000015.what could be the reason?if any body knows tell me the solution.
the title doesn't tell so much -- some code tried to access an object at an invalid address, this is the same as a 'segmentation fault' in user space. some of the millions of pointer variables has an invalid value (NULL) and the code (at some unspecified location) using this pointer didn't check.
without the full oops message you can't see what is happening and where. please post the full oops message. if you are lucky, the message was logged to /var/log/syslog or similar.
