If you don't have CONFIG_HPET turned on, my patch wouldn't help. Also, can you look up the bad address (e.g., f8881920) in /proc/kallsyms? When I reproduced it, the faulting address was hpet_acpi_driver. Maybe you've found a similar bug in a different driver. ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
