Comment 0 for bug 788804

I'm experiencing irregular lockups of my Efika MX Smartbook, which appear to be power-management related somehow.

Symptoms:
- The display becomes "frozen", with no corruption.
- The smartbook stops responding to any input, bar holding down the power button until it switches off completely.

More info:
- The lockups seemed to happen sooner when I was using xfce-power-manager, rather than gnome-power-manager (which leads me to believe it may be a power management/settings issue).
- The lockups occur whether on mains power or not.
- There are no relevant errors in any logs that I've been able to find. The last time I checked, the last log entry was a "gnome-power-backlight-helper" message (/var/log/auth.log), approx two minutes before the freeze (based on what the frozen panel clock showed). Any other entry was at least 10 minutes beforehand.

Please let me know what more information I can supply, or what I can try.
