Discussion:
loading 'acpiphp' fails after the system boot?‏

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 ��칻�&�~�&���+-��ݶ��w��˛���m�b��a��e�����ܨ}���Ơz�&j:+v�������zZ+

What happens in the 3.11 kernel release? Lots of work has been done in
this area in the past 2 years, please try a newer kernel. If there are
still problems, please let the linux-***@vger.kernel.org mailing list
know about it.

thanks,

Thank you for reply. I did not try 3.11 kernel. I will check 3.11 kernel and see. But I use 3.0 kernel as a requirement.

Thank You,
Shiro

Thank you for reply. I did not try 3.11 kernel. I will check 3.11
kernel and see. But I use 3.0 kernel as a requirement.
Then please contact the people who is in charge of that requirement, as
they are the only ones that can support you, the community can not.

Best of luck,
