Description Ali Abdallah 2008-06-16 13:51:49 UTC 
Latest working kernel version:
------------------------------
My memory stick reader used to work with kernel version 2.6.22.x and 2.6.23.x, but not with 2.6.20.x ( not tested with 2.6.21.x) .

Earliest failing kernel version:
--------------------------------
>=2.6.24

Distribution:
-------------
Slackware 12.1, and Ubuntu 8.04

Hardware Environment:
----------------------
06:00.0 FLASH memory: ENE Technology Inc ENE PCI Memory Stick Card Reader Controller
06:00.1 SD Host controller: ENE Technology Inc ENE PCI SmartMedia / xD Card Reader Controller
06:00.2 FLASH memory: ENE Technology Inc Unknown device 0720
06:00.3 FLASH memory: ENE Technology Inc ENE PCI Secure Digital / MMC Card Reader Controller

Software Environment:

Problem Description:
when inserting a memory card in the reader, nothing comes from /var/log/messages but dmesg shows 
mmc1: unrecognised SCR structure version 1
mmc1: error -22 whilst initialising SD card

searching over the net i didn't find anything useful, but it seems this SCR checking is only implemented in sd.c source with kernel version >=2.6.24, the card works perfectly with 2.6.23.x and with 2.6.22.x
