• If your system crashes at random intervals, perform a MemoryTest first before filing any bug reports or support requests
• 如果你的系统每过一段随机时间就崩溃，在填写bug报告或支持请求前请先进行一次内存测试。
• If your system crashes when a particular action occurs, and this is repeatable every time, try the following steps:
• 如果你的系统在某一特定动作发生时会崩溃，并且每次这种情况都相似（可重现），可以试试下列几步：
  • Try to reproduce the crash on a text console (`Control`+`Alt`+`F1`) if possible. If the crash occurs during startup, select the `recovery mode` option to disable the splash screen

如果可能，尽量在文本控制台(Control+Alt+F1) 里重现该系统崩溃 FIXME补完此句的翻译

• • When the crash occurs, press `Alt+SysRq+1` followed by `Alt+SysRq+t`. If using a text console, you should see a trace dumped to the screen. If the system is sufficiently alive, it will also be logged to `/var/log/kern.log` and visible in the output from `dmesg`. This information shows where the crash occurred, and should be included in any problem reports. If the output is not saved in any file, or the system is so bad off that you cannot retrieve it, you can either take a digital photo, or hand write the results. Almost all of the output is important (so please don't copy the one line you think is important, because context means everything).

当出现系统崩溃时，按下Alt+SysRq+1组合键，随后按下Alt+SysRq+t。如果正在使用文本控制台，你应当看到一组跟踪信息打印在屏幕上。如果系统还能苟延残喘，这些信息还会被记录到/var/log/kern.log文件中，并且可以在dmesg命令的输出中看到。该信息会给出崩溃肇始于何处，提交任何问题报告时都应包含这部分信息。 FIXME补完此段的翻译

• AnthonyBarker: I would recommend entering the Bios and changing the settings to default/fail safe. After troubleshooting strange video crashes on my computer for 2 weeks it turned out it was the AGP settings in the BIOS.
