Description:

It is impossible to either format a sdcard or write an image to it with dd or other tools. While formating (either with palimpsest, gparted or mkfs) the process just hangs without explicit errors. the dmesg shows the below listed errors.
Just using palimpsest under 13.10 gives the below listed error.

Its is possible to read from the card though and it is possible to write files <350 mb to the sd card. i used and cross checked four different sd cards which all worked nice on other systems.
The problem persists using the freshest kernel available, i tested it with 14.04 daily and arch live.

Another interesting fact is tha Ubuntu seems not to be able to load the relevant Firmware while booting up:
Failed to load firmware "tigon/tg357766.bin"
I already asked Broadcom for a firmware/driver for this netXtreme combo lan-sdcardreader chip, but they replied that they are not supporting Linux, although they have a driver downloadable for Linux at their Website.


Patch:

I found this patch which may be related/ be a solution for this Problem. But i dont know if this Patch is applieable against a actual Kernel, and i dont know how to use it in general.
