dmesg

I tried mounting a ISO file I have on my hard disk to /mnt, then copying the
data from the ISO file to my HDD, both the ISO file and all the data are in the
same HDD/partition.

Here is what I tried:

$ mount -o uid=1000 -t iso9660 /home/diego/tmp/Dead\ Space\ 2/flt-ds2a.iso /mnt
$ cp -a /mnt/* ~/ds

However, after a while of waiting for the data to copy, I noticed the HDD I/O
and CPU utilization stopped at all. I tried to kill the process but the machine
just froze, and I got tons of errors in dmesg (please see the file attached).

I tried to get the ISO file again, but the problem still persisted. I read this
ISO and game has some DRM on it, could this be the cause? The size of this ISO
file is about 5.5 GB.

I will try to reproduce the problem with other ISOs also and report back
anything I find.

My machine specs:

Intel(R) Core(TM)2 Duo CPU     E7500  @ 2.93GHz
Arch Linux x86-64
2 GB of RAM.
kernel 3.0.1

Thanks.
