Card Reader doesn't work if memory is inserted after boot

[Sergio Infante Montero (neosergio)]

Description: Ubuntu karmic (development branch)
Release: 9.10

I installed Ubuntu Netbook Remix Karmic 9.10 on my Acer Aspire One A150, and i expected that my card reader can read any memory card, but i can't read if i don't inserted before boot. Only when i insert the card before boot, i can read it. My chipset is JMicron jmb38x and I use linux kernel 2.26.31-14-generic

I solved temporally like this:

I modified /etc/default/grub on line

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”

and replace it for:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pciehp.pciehp_force=1″

 after that I type:

sudo update-grub

and finally reboot, and works.

Hi Sergio,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 453742

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I have the same problem on my Acer Aspire One 110 running Ubuntu Netbook Remix 10.04
None of the card readers (the standard or the storage expansion) detect cards unless you insert them before boot.

Sergio's workaround solve the problem.
