SD Memory Card Problems

[GreyGeek]

This is not good. Just completed clean install and exactly the same problem, no change. Seriously considering going back to 14.04LTS.

Why not just downgrade the kernel to a previous working version?

In reply to Greygeek, downgrading to 14.04 is 1 way of using a version 3 kernel which I know works. When I had the upgraded system which still retained version 3 kernels then I could simply boot into a previous version. Now I have done a clean install, these are no longer present and the version of 14.04 still available on the Kubuntu site uses a version 4 kernel. I did take a copy of the root directory before the clean install so maybe I could use these kernels.

What is frustrating is that it is probably a stupidly simple fault, I will report this as a bug to try and sort it out as it is better to go forward rather than back.

Don't downgrade the distro, JUST the kernel.

This just goes on & on. I copied over version 3 kernels I had backed up, did update-grub etc and it booted into a version 3 kernel. No WiFi although wired ethernet works OK. It allows me to go through the wireless configuration set-up but at the end the "connect" button stays greyed out. I have looked at the output of lshw and noticed the following differences :-

I could not see any other major differences. It seems to have recognised it but not initialised it properly. I am stuck again !

No. Reinstall the 4.4 kernel.
It seems that they've renamed the drivers for the rts5139. They are now labled rtsx_usb_***.ko
Here is what is on my system:

Do "lsmod" in a Konsole and check which module the kernel is loading as your card readers. IF it is not one of the three above then do "sudo modprobe -r whateveritis" and then "sudo modprobe oneofthethree"
Experiment and find out which one works for you, if any will. If one works then issue "sudo echo rtsx_whatever >> /etc/modules" to make it permanent.

I checked the kernel modules as described by Greygeek and everything is identical, modinfo rtsx_usb_**** all give exactly the same responses. Looking back at the dmesg outputs it seems the problem begins when it tries to attach the card as a scsi device. Could this be a scsi driver problem ?

Also, on the working kernel 3.13 system, the same module names are loaded. They are different files as the file sizes and srcversion nos. are different but it may be worth copying the working modules to the kernel 4.4 system just to see what happens.

[GreyGeek]

Did you do an "lsmod" in a Konsole and check to see which wireless driver your system is using? You may have to blacklist the one the kernel is trying to load.
