When I tried to copy around 500Mb of files between two filesystems on the
same hard-drive, I got the following message on the console:
hda: error: DMA in progress...
and the system seems to get stuck - I can't kill the cp with ctrl-c, nor
can I get getty to let me log in on another console.
However, the kernel still forwards IP traffic and I presume is managing to
tickle my hardware watchdog as the system doesn't automatically reboot.
Hopefully, the relevant part of my boot output follows.

When I am not doing intensive disk activity, it seems to last longer - it
has been up one and a half hours so far and hasn't crashed yet, doing a
mixture of mail reading and running distributed.net.
