Hi All, In kernel version 3.0, when ‘apciphp’ driver module is loaded, after the system comes up, it fails with error “no such device”. When I tried to debug I see that it fails in acpiphp_get_num_slots () function with error "Total 0 slots". In this case ‘bridge_list’ seem to be NULL. But when the ‘acpiphp’ is loaded during boot time, it seems to work file. Where does the ‘bridge_list’ get populated and why does loading ‘apciphp’ after the system comes up fails to load. Regards, Shiro ��.n��������+%������w��{.n�����{��-�[��)��jg��������ݢj����G�������j:+v���w�m������w�������h�����٥
