| 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.
