Hi, I have the same problem with 9.04 (Jaunty 64 bit = 2.6.28-11) on a Dell XPS M1330, with the internal Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 22). The same SD cards work perfectly on an external USB reader. I didn't have any problem on Intrepid 32 bit.
Following a similar bug (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/323159) I've found a simple workaround - add the line: blacklist sdhci to /etc/modprobe.d/blacklist.conf Hope this helps ;-)) ** Attachment added: "dmesg output" http://launchpadlibrarian.net/28027078/dmesg.txt -- Ricoh R5C822 SDHC Card reader I/O errors https://bugs.launchpad.net/bugs/247819 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
