Strange bug freezing my laptop

[Julien Olivier]

Today, I let my laptop running all day long. When I came back, it was
still working but the hard disk's led was on. All _seemed_ to work as
normal but going to a virtual console (CTRL-ALT-1), I saw several error
messages like stating there was an I/O error trying to access /dev/hda3.
And every app had problems: rhythmbox couldn't play music anymore,
complaining about missing plugins, evolution couldn't save messages
because it couldn't write on the hard drive etc... I rebooted my laptop
and all was OK again...

Does that sound familiar to anyone ? Should I try appending ide=nodma to
grub.conf ?
