Long shot, but I had random freezes on a machine years ago and it turned out that I forgot to install the intel-ucode package [1]. EDIT: I realize now that you're running an AMD cpu. Also, things that may help you track this down: - monitor /proc/interrupts when it freezes - remove some hardware, see if crashes disappear, add back progressively - increase kernel verbosity (I forgot how I did this, maybe [2] will help?) - when and how exactly did it start? > Definitely worth checking memtest86+ Keep in mind that it may take days of stress testing memory before catching an error. I caught a faulty RAM slot on a MB once after 3 days of running memtest. I suggest running for an entire week.
