| From: Christopher M. Penalver | Date: Sep 2 11:09:17 2014 -0000 | | Jim Bednar, please test the latest mainline kernel via | http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc3-utopic/ . If for | whatever reason it doesn't work out, one may uninstall it as advised in | https://wiki.ubuntu.com/Kernel/MainlineBuilds .
I installed the new kernel on my normal setup as described there, but ended up with a kernel panic "no init found" on reboot. So I removed it and ran "sudo update-grub", which brought everything back to normal. In any case, the good news is that at least as of today, SD card reading is working just fine on this machine, even with the stock kernel (3.13.0), before and after installing and uninstalling the new kernel! There have been some Ubuntu updates installed over the past couple of days (not sure what), and maybe that fixed it? Or maybe it's flaky hardware, and it will stop working in a few days or on the next reboot. Note that lspci still says "Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5227 PCI Express Card Reader (rev 01)", but I can read files on the cards just fine.

However, SD cards are not recognized for my Lenovo Thinkpad X240 running the much later release Ubuntu 14.04 with kernel version 3.13.0, for which lspci reports: 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5227 PCI Express Card Reader (rev 01) That appears to be the same symptom as when there was no support at all. Any idea what happened to the support for this SD card reader, or what I can do to work around it?
