Thanks, and sorry for the slow reply. If I understand correctly, the sequence of events are these: 0. 2.6.32-45 is booted 1. insertion of USB stick 2. system mounts USB stick 3. right-click on it and choose "safely remove drive" 4. display turns black, though mouse pointer is still showing, kernel panic (blinking keyboard LEDs) If you can get a log of the boot and kernel panic using a serial console[1] or netconsole[2], that would be perfect. Hope that helps, Jonathan [1] http://www.kernel.org/doc/Documentation/serial-console.txt [2] http://www.kernel.org/doc/Documentation/networking/netconsole.txt -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".

I've checked the dpkg.log file on one of the systems on which I'm certain I switched to a 3.1 kernel because of this bug, and the last 2.6.32 kernel on it before I switched is 2.6.32-39. The 3.1.5 kernel I installed at that time did not have the bug. We're really going to need a kernel log in order to make any progress on this. I'll try to reproduce this on a test system, but I leave on holiday in a few hours so it could take a while.

Bug#675621: system freeze after safely unmounting usb drive
reassign 675621 linux-2.6 thanks Hi, I have seen similar crashes with the 6.0.x kernel on some of our systems. Unfortunately the systems are in a remote location and I was unable to capture any crash screens. I installed the 3.2 kernel from squeeze-backports on those systems and that fixed the bug. Can you try installing the linux kernel from squeeze-backports and confirm if this fixes the issue for you? See [1] for instructions on how to enable the backports repository. Please also attach the system log (/var/log/syslog) as it might contain more information about the crash. If you switch to a non-graphical console before unplugging the memory stick, does it show any messages? Press ctrl-alt-f1 to go to a non-graphical console and then unplug the usb stick. If a crash message appears, try taking a photograph of it and attach it to this bug report.
