Debian freezing

[ayu]

I have had my Debian Squeeze installation for a pretty long time now (since December last year), and I have never had any issues with it.
Until yesterday, when I started a large file transfer from my server to my desktop (both of them have Debian, but the issue resides on the desktop) and all of a sudden the system froze.
I then restarted and tried again, and every time I started the transfer, the system would either freeze or restart.

Today when I woke up and did my "daily routine surfing news ..blabla etc" it just randomly froze again for no apparent reason.
I decided to take a peek in the syslog, and this is what I found, spammed all over it at the time when the machine died.

There is one more key thing that I want to mention, but I want to wait until someone can give me an idea of what these errors means more exactly.
That is, I have a clue on what the error could be, but I want to be sure of it.ä

Any help would be greatly appreciated.

hm, I have read of a kernel bug in context with the ATA ACPI, create /etc/modprobe.d/options.conf (if it doesn't exist) and enter:

Code: Select all

options libata noacpi=1

and see if it helps after a reboot...
