Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am running sarge with the 2.6.8 kernel. I'm running it on a Dell Inspiron 1100 laptop. When I plug my usb cd/dvd rw drive in, it works fine. When I umount it it unmounts. But when I then unplug it, the system freezes. It doesn't happen immediately, it seems to happen as I am accessing the Applications or Actions menu. I don't know how to troubleshoot this. Is there a log file that would record this?
you unplug after you unmount you said, right?
when you mount the drive check 'dmesg | tail'.. then go open a file on the drive or something and check the same command.. unmount it and check the same command.. then finally unplug it and check the same command. or post the output of the last two here if it doesnt say anything logical.
after unplugging, if you dont touch anything and leave it for awhile, will it still freeze?
The device mounts automatically when I plug it in. When I plug it in, access a file an unmount it, dmesg | tail is the same:

When I unplug it, I get the following (dmesg | tail doesn't catch it all, so I saved dmesg):

As far as I have experienced debian is the only distro that this happens with. It doesn't happen with slackware or fedora core, or even ubuntu. It happened when I was trying out etch also. It's the only persistent problem I've had with debian. If I could solve it, this would be the "perfect" distro.
do you have a live cd on hand? or are you dual booting any of those other distros that worked fine with this? if so check the output of their dmesg and mount to see what device file its mounting.
sorry im of no help! im interested to see the answer, im still looking.. hope someone can help you.
is there a /etc/rc.d/rc.hotplug file that is executable? if not try and make it executable so it runs at startup.. try booting with the device plugged in.
