I'm running xubuntu 12.04 on my Acer 756 netbook; everything works except for the sdcard: It does not show up under lspci (I tried to boot with or without the sdcard inserted). It does work in window 7. After some digging I found this thread
(note that this thread is for the atom netbook whereas the 756 is bascially sandy bridge, which is why I start a new thread). I tried the various suggestions in that thread but none works. The suggestions in post #70 there does help a bit:
(1) edit /etc/default/grub with
GRUB_CMDLINE_LINUX_DEFAULT="pciehp.pciehp_force=1 pciehp.pciehp_poll=1 elevator=noop quiet splash"
(2) add to /etc/moduels
And if you reboot the machine WITH THE SDCARD then it works! And lspci gives
04:00:1 SD Host controller: Broadcom Corporation Nextreme BCM57765 Memory Card Reader (Rev 10)
Unfortunately, if you umount the card and reinsert it the card is not longer recognized.
This is driving me crazy... any help and suggestion is most appreciative!
