SD Cards not working in FC17
On my Acer Aspire One 756-2623 netbook running Fedora Core 17 I am having trouble mounting SD Cards. Once in a while if I do a cold boot with an SD card in the drive I will be able to see it after the system boots. Below is all the steps I have taken and diagnostic data I can think of and find on this and Fedora Core's forums. I appreciate any suggestions you can make.
Code:
# uname -a Code:
# modprobe -r sdhci Code:
# dmesg |
"Invalid iomem size. You may experience problems."
I would have a look at boot parameters for using one for your subject http://www.mjmwired.net/kernel/Docum...parameters.txt quirks.. pci.. related to iomem..? Just an idea (one time I had a SD card making few messages during boot and the messages could disappear by using a boot code; this was NOT your issue here.. but perhaps a similar topic?). |
From what you just sent me [MSI Message Signaled Interrupts (PCI)] looks interesting as it relates to a different way PCI uses interupts? I will have to see if using this option has makes any change. Thanks for your reply I will report back.

pci=nomsi did not work for this issue out of the box. After I put the system to sleep for a long period and woke it up it did see the card in the drive. I am uncertain if it was due to the option or unrelated. I will have to do some more testing. Any more ideas would be appreciated.

disconnect interrupt routing with a bootparameter?
according google "timeout waiting for hardware interrupt", the issue seems a kernel issue; so, a kernel parameter could solve? Which one? dont know. I will read a bit more when I have time and post here again if I have another idea. |
I tried debug_quirks=0x40 without success.
I did find that if I plug in Ethernet cable it works perfectly. The wired network also must be enabled it appears. |
Great.
Post both dmesg.txt (in a terminal make dmesg > dmesg.txt) here after 1. boot without LAN cable (your SD card has issues) 2. boot with LAN cable (SD card recognized) We should look at the differences and try to understand what is going on (in relation with LAN card activation). I started a look at the boot parameters.. quick guess would be apci=noirq or acpi_irq_balance acpi_irq_pci="IRQ" where the "IRQ" the IRQ is when your cable is in. I dont have the HW, so Im a bit in the dark. or.. Bug? have a look at https://bugs.launchpad.net/ubuntu/+s...x/+bug/1067222 A bug report says "apport-bug bios-outdated i386 kernel-bug-exists-upstream kernel-bug-exists-upstream-v3.6.2-quantal needs-firmware-check precise regression-release running-unity staging". Perhaps a workaround exists before the kernel is upgraded. or here http://osdir.com/ml/ubuntu-bugs/2013-01/msg01739.html "In addition I had a talk with a nice gui with broadcom-knowledgeâ. It looks like this card has an additional (private) mmio-block above the normal 0x100 bytes in the PCI bar." Im scratching my (small) head to understand how to go around it. Contact these guys? or broadcom; they should know a workaround? |
Sorry I have been traveling. I will try to put a dmesg up here soon. I think this is a bug at this point, I am just unsure were to file it, Fedora does not seam to be appropriate as it is somewhat crossing the distribution divide. Thanks for your continued help.
