Yehaaaw! That reader can be found on DELL X300 too. It works almost fine for me, see attached dmesg. These I/O errors didn't prevent me from mounting a card, though. > In order to write this driver I hacked qemu to have access to the cardbus > bridge containing this card.

I tried to set TIMEOUT to 1000 (this is a slow card) without better results. Tell me if there are things I can test. I'm not subscribed to linux-kernel, so please remember to Cc me when posting updates, etc. so I can test them. Samuel
