Comment 55 for bug 258446

Thanks a lot to ceg!!! Now I have working properly my JMicron card reader on my Acer 5737z even if the card is not inserted during boot time.
Nevertheless all tests were done with SD and microSD cards, other type of cards must be test additionally
Here is a little workaround:
1. Remove all parametr pciehp.pciehp* from /etc/default/grub (grub2)
2. Update your grub2 config: update-grub2
3. Reboot
4. Insert module acpiphp to kernel "sudo modprobe acpiphp"
5. Try to insert card to cardreader.
6. You can add string to /etc/rc.local before string "exit 0" to automaticaly loading this module during startup.

[wados@acer:/]$ cat /etc/rc.local
#!/bin/sh -e
# By default this script does nothing.

modprobe acpiphp
exit 0
