For about a week, my workstation has been crashing every day or so. |
| 2 |
Typically it happens late at night while BackupPC is backing up a hard |
| 3 |
drive. With "tail -F /var/log/messages" running I saw EXT3 mentioned a |
| 4 |
few days ago and started suspecting a hard drive problem. |

|

Last night it happened again. This time my "tail ..." window was |
| 7 |
opened full screen so I saw all the messages and know more. Here's |
| 8 |
part of what I wrote down (until I got tired of writing): |

I'm running a 2.6.25-gentoo-r7 |

To learn more about what's happening (and to more easily record |
| 22 |
all the kernel messages), I'm now running "tail -F /var/log/messages" |
| 23 |
from a second machine (via an SSH session). |

Questions: |
| 26 |
|
| 27 |
Is there a better way to capture the full BUG output??? |
| 28 |
Once I have the full BUG output, what's the next useful thing to do? |
