Trying to delete images from a Canon Ixus 60 that is connected by the original USB cable from within digikam seems to kill access to my harddrive.

By kill I mean the following. The system seems to be unable to read anything that's not in file buffers. Login e.g. on terminal is impossible. Upon entering the username the terminal restarts. Ctrl-Alt-Backspace kills the X-Server but it doesn't come back. Ctrl-Alt-Del in KDE does not work. It is also not possible to start a system shutdown via the "Start"-Menu. Powerbutton does not work. Only way to recover the computer is hard power-off/reset.

On terminal 10 the following message is shown:
eddie kernel: ehci_hcd 0000:00:02.1: HC died; cleaning up Disabling IRQ #23

After a while it starts printing out disk access errors. After a restart fsck replays a journel and may raid 5 used for /home in some cases has to be started manually as it's superblocks seem not to be in sync (it starts up fine with -force, so. In the first attempt, where I had waited for a while before forcefully shutting down the system it afterwards synced for a while, so).

In one occasion it showed a dump on console 10. I attached two pictures of it.

Deleting files from the camera using konqueror (system:/media/camera) seems to work fine. I was also able to delete some single pictures from the cam, but anytime I tried to delete multiple pictures all at one time it crashed the mashine.

The installation is an upgrade to 11.0 from 10.3 on which the problem did not appear, therefore I am pretty confident it's not some hardware problem like conflicting IRQs or so.
