Public bug reported:
I have a q-tec external USB harddisk case with a 250 Gb harddisk.
When I use this harddisk to render films or use it intensively in another way,
quite often the system hangs. If I, without restarting linux, just pull out the
power cord of the external disc, Ubuntu starts to run again and (off course)
displays a message of an unsafe removal of the disc.
I have looked at other soft-lockup bugs but when the lockups occur there is no
wireless card in the computer (which in a lot of other reports is part of the
problem). The lockup also only happens when we use the harddisk intense, i.e.
using rhythmbox with music stored on the harddisk gives NO problem, but
rendering videos with cinnelera does. It also happens when I for example try to
do a simple backup with tar of my home directory to the external drive (and
that does not use exotic stuff).
My computer is a IBM A31 laptop with 1 Gb of mem and 20 Gb HD.
The external HD is connected through a PCMCIA firewire/USB2.0 combo card (which
might also be part of the problem, that I can not tell).
