I know that the number followed by 'Oops: ' contains some information about the kernel oops including 'read/write' or 'kernel/user mode' or 'page not found/protect fault'.
Could you explain the meaning of the number, '817'?
Code:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
Internal error: Oops: 817 [#1]
CPU: 0
pc : [<c00f2268>] lr : [<c01f89f0>] Not tainted
