       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I have just installer Ubuntu Dapper Drake, having kernel 2.6.15-15-386 installed. Here, my Winbond SD Card reader (built into my PC) worked fine, reading my cards.
When I upgraded to kernel 2.6.15-16-686 (or 386), the card reader suddonly stopped working, but still works fine, when I boot into 2.6.15-15-386.
It seems, that the card reader is not found at all.
