Realtek Card Reader not working (kernel driver)

[Zibri Soft]

This is the situation if I use the normal 4.13 kernel driver

[ 1899.245301] mmc0: cannot verify signal voltage switch
[ 1899.377540] mmc0: new ultra high speed SDR104 SDXC card at address e624

[ 1900.240084] print_req_error: I/O error, dev mmcblk0, sector 8

but it works perfectly if I use the patched driver on kernel 4.4-4.7
this one https://github.com/Zibri/Realtek-rts5229-for-4.4-kernel

the problem is that I can't compile it on 4.13 and anyway this affects a lot of systems using 5229/5227

many laptops use this.

any solution??

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1735099

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Nevermind, I successfully compiled the module on 4.13 kernel...
But can I ask what is wrong in the main kernel module?
Can someone fix it?

[Zibri Soft (zibri-)]

https://github.com/Zibri/Realtek-rts5229-for-4.4-kernel

is now updated accordingly.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

And I also confirm that with my patched driver it works.

Thank you for providing a patch, and making Ubuntu better.

Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc?

People affected by this bug are probably wondering why the kernel team doesn't just apply the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch to a stable kernel that is not from upstream. Applying patches that don't come from upstream add greatly to the support of the kernel as other upstream patches may touch the same area as the non-upstream patch and may prevent them from applying cleanly.

To submit your patch, send your patch with the detailed description/changelog and your Signoff (ending with Signed-off-by: your name <email>), to the emails listed from ./scripts/get_maintainer.pl drivers/SUBSYSTEM-DETAILS (the get_maintainer.pl is from the kernel sources). Once you have sent the patch upstream and it's accepted, please drop a note here so that we can cherry-pick/include the patch into Ubuntu kernel.

The linked github repository doesn't break out whatever the fix is to the rtsx_pci driver is. Therefore it is all but impossible to figure out what was changed.

Another user reported this today with 5.0.0-27-generic where 64GB cards are readable but 256GB cards are not. It isn't clear if the power-signalling errors are critical or incidental:

[Austin (austinagronick)]

Just wanted to update, I am the user TJ is referring to. The issue was resolved after running "sudo update-initramfs -u" after the commands in the readme of the linked github repository as detailed here: http://baby-panda.github.io/linux/RTS5229_driver/

The new driver installation be verified by running "lspci -v"

[TJ (tj)]

Austin, thanks for confirming that repository solves the issue for you. I'll try to make a diff of the original commit to that repository against the Linux mainline driver at the same date, maybe we can be lucky and it'll make the required change clear so we can test it in Ubuntu and then get it into mainline kernel.

Please keep a watch on this report for updates.

Just to be clear the device Austin is dealing with is:
