Ok, reading here (http://mmc.drzeus.cx/wiki/Controllers/TexasInstruments/FlashMedia) I found a partial workaround using sudo setpci -s 06.3 4c=0x22
Then when I insert the card the driver react again to the insertion: [ 156.431818] mmcblk0: mmc2:494e SD 493568KiB [ 156.431846] mmcblk0: p1 However the card is not automatically mounted as it was before in Dapper, so maybe there's something else related. And however it is stil open the question why in dapper I didn't need to use setpci (maybe it was hardcoded in some way?) -- sdhci driver doesn't recognize anymore my sd card reader https://launchpad.net/bugs/55507 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
