Firstly, 8-current means you're running a build more than 3 months old.
Have you considered upgrading?

When the lockup occurs, are you in X11 or on a VTY?  If the latter, is
there anything relevant on the console?  Does the keyboard work at all
(Caps-lock and/or Ctrl-Alt-ESC)?

What (if any) power management are you running?  Do you have acpi_throttle
enabled - if so, you could try disabling it.

Finally, some more details of your system would be handy.
