As Patrick mentioned, this is probably an ACPI problem and you should
review the wikipage. Linux is a lot more tollerant of bad tables. You
should review the dmesg for problems that Linux gets past. You may
also want to run the ubuntu fwts. It has a lot of ACPI tests built in.
For windows, you should set windows to BSOD instead of reset. You may
need to connect the windows debugger to get more information from the
ACPI daemon.

We have been fixing a number of issues in the AMD fam14 and fam15tn ACPI tables.

You should review these changes:
