Kernel Bug Tracker – Bug 23212
multifunction card reader of acer aspire one stopped working
Last modified: 2010-12-05 19:47:59 UTC
On acer aspire one A110L, the multifunction card reader (on the right side, with jmicron module) stopped working with 2.6.36.
It is not detected anymore by the kernel. Perhaps a problem with pciehp module.

DMESG of 2.6.36

DMESG of 188.8.131.52 (the card reader works)
Could I persuade you to try a git bisect between 2.6.35->2.6.36 on this, please? Let me know if you don't think you can do that, or would like some help.
Thanks for the report!
Thibault, here's an update from bug #16119 by Eugene Shalygin:
"trick has changed from "pciehp.pciehp_force=1" to "pcie_ports=native
pciehp.pciehp_force=1" in my case with kernel 2.6.36"
I hope this'll solve your problem.
Thanks a lot, "pcie_ports=native" solves the problem !
