SD Card Reader Incomplete / Corrupt Files

[martin]

Binary package hint: nautilus

This is a repeat of bug 649912 which seems to have gone cold since the last release, but is present in exactly the same form in 11.04.

HP 6700 Series Laptop with built-in SD (and multi-) card reader.

SD card reader displays incomplete or corrupted files. Eg, jpgs shown as random coloured thumbnail or random characters. Some files are not displayed at all. Some files are correctly displayed.

Opening an affected file (if you can see it) does not work. Different error messages occur - 'could not open file' or 'type not supported' 'could not display' etc. Some correctly displayed files also yield these messages.

Ejecting the card usually results in Nautilus closing/crashing. In some cases browsing the file structure or attempting to open some files also crashes Nautilus. When it closes there is no prompt for bug report.

The card reader was a problem a couple of years ago (8? Series of Ubuntu) on my HP Laptop - simply didn't work at all but since Karmic/Lucid it's worked flawlessly.

The bug is present in 10.10 and 11.04 (no change or improvement). 10.04 works perfectly.

I am having the same problem with my HP dv5 laptop. I am currently running Ubuntu 11.04 Beta.

I am having the same problem with my dv7t (JMicron Card Reader). This seems to be the patch:

Thanks Amir, unfortunately implementing the patch is beyond me but I guess if it exists that means someone should be able to integrate it into Ubuntu in a future version. It's all a bit of a shame though, as there was no problem in 10.04 and versions before that.

Just a note, the behaviour is exactly the same with Opensuse 11.4, but I suppose this is to be expected if it's based on the same kernel.

The patched kernel is here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.0-rc1-oneiric/
but actually disposable only for 64 bit systems

[Fabio Marconi (fabiomarconi)]

Here's the patch to fix this

[martin (braaart)]

Hi Fabio, great! Thanks. Will this come out via a future update or must I manually insert the patch? If so how?

[Seth Forshee (sforshee)]

I made a test build with the purported fix applied. It is available at:

http://people.canonical.com/~sforshee/lp766539/linux-2.6.38-10.44~lp766539v201106061540/

Please test it to confirm that it fixes the issues and report your results back here. If the patch is confirmed to fix the issue then it will be incorporated into a future upate. Thanks!

[Seth Forshee (sforshee)]

It's been several months since I requested testing, and there has been no response. The supposed fix is present in oneiric, so I'm closing as Fix Released. If anyone wants to verify the fix for natty, we can add a natty task at that time.

I just updated 11.04 64-bit and this bug still affects me. The last release that works for me is 10.04. Can I somehow check if my problem is due to the same bug,, or if the patch has been applied in my kernel? Thanks!

[Seth Forshee (sforshee)]

Halkola: You should go ahead and open a new bug by running 'ubuntu-bug linux' in a terminal. Thanks!

[martin (braaart)]

Still having the same problem in 11.10. Have re-launched a new bug 875927.

Thanks Seth and Martin. I have marked that the new bug opened by Martin also affects me.
