Sd Card Readers

I am running an Acer Aspire One on ubuntu 9.10 NOT the netbook remix version but the desktop version. Everthing works except my sd card readers are not hot swapable. Can anyone instruct this newbie how to get them to work. I f someone could take me through it step by step please.

 

if you have grub2 you should have if you did a new install here is a procedure that worked for me:

open a terminal and type
gksudo gedit /etc/default/grub

on line #9 add 'pciehp.pciehp_force=1' as shown below::
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pciehp.pciehp_force=1"

then save & run "sudo update-grub"

if you happen to have regular grub this should work:

gedit /boot/grub/menu.lst

find the kernal line and add 'pciehp.pciehp_force=1'
kernel /boot/vmlinuz-2.6.31-14-generic pciehp.pciehp_force=1
and save

hope that helps

Hello All

I am running ubuntu 9.1 (fresh install) on Aspire zg5 that has been upgraded to 1.5 gigs and the wireless changed to a dell 1505 N card. I have made the changes to the files for grub2 listed above and neither of the readers work unless I have a card in them at boot. Both work correctly then but no hot swap joy. Is there any thing else I need to do to make this work? The install went perfect and everything else except brightness osd works 100% I love ubuntu so far and find that I boot it more often than xp (dual boot).

Any help would be appreciated.
