Feisty Fawn and Texas Instrument Card Reader

If you have an Multimedia Card Reader 5 in 1 from Texas Instruments, if you don't know, use this command to confirm:

$ lspci | grep "Multimedia Card Reader"
05:06.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD)

You will not be able to use this card reader with new Ubuntu 7.04 (Feisty Fawn), because there are some problems with tifm (Texas Instruments modules) and MMC core on kernel 2.6.20. The discussion on linux kernel mailing list is here.

Alex Dubov, the maintainer of tifm, said that:

Unfortunately, driver shipped with 2.6.20 is buggy. Please use the standalone version of the driver, for a time being.

So if someone has this device, the solution is:

1. Download the device module: http://prdownload.berlios.de/tifmxx/tifm-0.8d.tar.bz2
2. Compile (you need the package build-essential ):

$ mkdir tifm; cd tifm
$ tar xvfj tifm-0.8d.tar.bz2
$ make
$ sudo make install

Now you have tifm working standalone. You have to reboot or reload modules for correct use. Remember that every time you have to upgrade your kernel, you need to re-run "make install".

Pavel warned me that this problem is history in kernel 2.6.20-11.18:

Big "Thank you" for our core developers. :-)
