FWIW I have seen something similar on my workstation with up-to-date F16
x86_64 with GNOME3. The ATI HD57xx card heats up to more than 90C even
when I was just typing an email in Thunderbird and nothing else loaded.
I also had several total lock-ups. I could not ping the box and reaching
it with ssh failed. I have not been able to find the cause. After I
installed the proprietary Catalyst drivers I have not seen any lockups
anymore. And the fans in the workstation are much quieter so temperature
seems to have dropped also.
Regards,
Patrick
