| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 1 | [Some of this is taken from Frohwalt Egerer's original linux-kernel FAQ] |

 | 3 |      What follows is a suggested procedure for reporting Linux bugs. You | 
 | 4 | aren't obliged to use the bug reporting format, it is provided as a guide | 
 | 5 | to the kind of information that can be useful to developers - no more. | 
 | 6 |  | 
 | 7 |      If the failure includes an "OOPS:" type message in your log or on | 
 | 8 | screen please read "Documentation/oops-tracing.txt" before posting your | 
 | 9 | bug report. This explains what you should do with the "Oops" information | 
 | 10 | to make it useful to the recipient. | 
 | 11 |  | 
 | 12 |       Send the output the maintainer of the kernel area that seems to | 
 | 13 | be involved with the problem. Don't worry too much about getting the | 
 | 14 | wrong person. If you are unsure send it to the person responsible for the | 
 | 15 | code relevant to what you were doing. If it occurs repeatably try and | 
 | 16 | describe how to recreate it. That is worth even more than the oops itself. | 
 | 17 | The list of maintainers is in the MAINTAINERS file in this directory. | 
 | 18 |  | 
 | 19 |       If it is a security bug, please copy the Security Contact listed | 
 | 20 | in the MAINTAINERS file.  They can help coordinate bugfix and disclosure. | 
 | 21 | See Documentation/SecurityBugs for more infomation. | 
 | 22 |  | 
 | 23 |       If you are totally stumped as to whom to send the report, send it to | 
 | 24 | linux-kernel@vger.kernel.org. (For more information on the linux-kernel | 
 | 25 | mailing list see http://www.tux.org/lkml/). | 
 | 26 |  | 
 | 27 | This is a suggested format for a bug report sent to the Linux kernel mailing  | 
 | 28 | list. Having a standardized bug report form makes it easier  for you not to  | 
 | 29 | overlook things, and easier for the developers to find the pieces of  | 
 | 30 | information they're really interested in. Don't feel you have to follow it. | 
 | 31 |  | 
 | 32 |       First run the ver_linux script included as scripts/ver_linux, which | 
 | 33 | reports the version of some important subsystems.  Run this script with | 
 | 34 | the command "sh scripts/ver_linux". | 
 | 35 |  | 
 | 36 | Use that information to fill in all fields of the bug report form, and | 
 | 37 | post it to the mailing list with a subject of "PROBLEM: <one line | 
 | 38 | summary from [1.]>" for easy identification by the developers     | 
 | 39 |  | 
 | 40 | [1.] One line summary of the problem:     | 
 | 41 | [2.] Full description of the problem/report: | 
 | 42 | [3.] Keywords (i.e., modules, networking, kernel): | 
 | 43 | [4.] Kernel version (from /proc/version): | 
 | 44 | [5.] Output of Oops.. message (if applicable) with symbolic information  | 
 | 45 |      resolved (see Documentation/oops-tracing.txt) | 
 | 46 | [6.] A small shell script or example program which triggers the | 
 | 47 |      problem (if possible) | 
 | 48 | [7.] Environment | 
 | 49 | [7.1.] Software (add the output of the ver_linux script here) | 
 | 50 | [7.2.] Processor information (from /proc/cpuinfo): | 
 | 51 | [7.3.] Module information (from /proc/modules): | 
 | 52 | [7.4.] Loaded driver and hardware information (/proc/ioports, /proc/iomem) | 
 | 53 | [7.5.] PCI information ('lspci -vvv' as root) | 
 | 54 | [7.6.] SCSI information (from /proc/scsi/scsi) | 
 | 55 | [7.7.] Other information that might be relevant to the problem | 
 | 56 |        (please look in /proc and include all information that you | 
 | 57 |        think to be relevant): | 
 | 58 | [X.] Other notes, patches, fixes, workarounds: |
