early hacksThis post http://ubuntuforums.org/showpost.php?p=10842957&postcount=62 shows a way that works for me to re-scan and detect slots that now have a card in (although the card may need to be removed and re-inserted).
sudo echo 1 > /sys/bus/pci/rescan
Tricks here http://ubuntuforums.org/showpost.php?p=10842957&postcount=62 that use
setpcidon't work for me, failing to select the device if it isn't already detected, or the
pciehpdriver which doesn't seem to be present on my installation.
SuccessI got auto-detection to work by following these tips https://bugs.launchpad.net/ubuntu/+source/linux/+bug/258446/comments/61 by adding the following files to
rebooting, and running:
update-initramfs -uso that those modules would be built in to the ramdisk; and then rebooting again.
Nothing else was required; no use of
pciehp, no edit of
/etc/default/grub.confand no creation of files in
