+Introduction
+============
+
+Always try the latest kernel from kernel.org and build from source. If you are
+not confident in doing that please report the bug to your distribution vendor
+instead of to a kernel developer.
+
+Finding bugs is not always easy. Have a go though. If you can't find it don't
+give up. Report as much as you have found to the relevant maintainer. See
+MAINTAINERS for who that is for the subsystem you have worked on.
+
+Before you submit a bug report read REPORTING-BUGS.
+
+Devices not appearing
+=====================
+
+Often this is caused by udev. Check that first before blaming it on the
+kernel.
+
+Finding patch that caused a bug
+===============================
+
+
+
+Finding using git-bisect
+------------------------
+
+Using the provided tools with git makes finding bugs easy provided the bug is
+reproducible.
+
+Steps to do it:
+- start using git for the kernel source
+- read the man page for git-bisect
+- have fun

[Sat Mar 2 10:32:33 PST 1996 KERNEL_BUG-HOWTO [email protected] (Larry McVoy)]
This is how to track down a bug if you know nothing about kernel hacking.
@@ -90,3 +143,63 @@ it does work and it lets non-hackers hel
because Linux snapshots will let you do this - something that you can't
do with vendor supplied releases.
+Fixing the bug
+==============
+
+Nobody is going to tell you how to fix bugs. Seriously. You need to work it
+out. But below are some hints on how to use the tools.
+
+To debug a kernel, use objdump and look for the hex offset from the crash
+output to find the valid line of code/assembler. Without debug symbols, you
+will see the assembler code for the routine shown, but if your kernel has
+debug symbols the C code will also be available. (Debug symbols can be enabled
+in the kernel hacking menu of the menu configuration.) For example:
+
+ objdump -r -S -l --disassemble net/dccp/ipv4.o
+
+NB.: you need to be at the top level of the kernel tree for this to pick up
+your C files.
+
+If you don't have access to the code you can also debug on some crash dumps
+e.g. crash dump output as shown by Dave Miller.
+
+> EIP is at ip_queue_xmit+0x14/0x4c0
+> ...
+> Code: 44 24 04 e8 6f 05 00 00 e9 e8 fe ff ff 8d 76 00 8d bc 27 00 00
+> 00 00 55 57 56 53 81 ec bc 00 00 00 8b ac 24 d0 00 00 00 8b 5d 08
+> <8b> 83 3c 01 00 00 89 44 24 14 8b 45 28 85 c0 89 44 24 18 0f 85
+>
+> Put the bytes into a "foo.s" file like this:
+>
+> .text
+> .globl foo
+> foo:
+> .byte .... /* bytes from Code: part of OOPS dump */
+>
+> Compile it with "gcc -c -o foo.o foo.s" then look at the output of
+> "objdump --disassemble foo.o".
+>
+> Output:
+>
+> ip_queue_xmit:
+> push %ebp
+> push %edi
+> push %esi
+> push %ebx
+> sub $0xbc, %esp
+> mov 0xd0(%esp), %ebp ! %ebp = arg0 (skb)
+> mov 0x8(%ebp), %ebx ! %ebx = skb->sk
+> mov 0x13c(%ebx), %eax ! %eax = inet_sk(sk)->opt
+
+Another very useful option of the Kernel Hacking section in menuconfig is
+Debug memory allocations. This will help you see whether data has been
+initialised and not set before use etc. To see the values that get assigned
+with this look at mm/slab.c and search for POISON_INUSE. When using this an
+Oops will often show the poisoned data instead of zero which is the default.
+
+Once you have worked out a fix please submit it upstream. After all open
+source is about sharing what you do and don't you want to be recognised for
+your genius?
+
+Please do read Documentation/SubmittingPatches though to help your code get
+accepted.
