For me too every time I do an apt-get upgrade, I have to let the machine there for a while because it becomes unusable. The mouse is always freezing and everything is lagging with the iowait at avoir 80%.
I have a AMD Athlon 64 with 2 gigs of RAM and a SATA drive. Changed the harddrive too and the problem is still there. Very frustating.
