If it does work, we will submit it to up= stream kernel. I own a Lenovo Thinkpad T440s as well just as the original bug submitter (Philipp) and that patch by Wei does not fix the problem for me (I applied = it to a 3.18 tree). What does work is to follow Philipp's instructions to patch the out-of-tree driver from realtek.com.tw. That module then gives me my SD card as /dev/sd= bX. Weirdly, my SD card reader used to work (but presented the SD card as /dev/mmcblk0pX). I do not know why it stopped working though as I didn't re= boot my laptop for several months. Running an older kernel version (3.14 for example) does not fix the problem. Maybe it is related to other parts of my (Debian testing) OS. I'll see if I can find a Debian unstable snapshot that restores the behaviour I observed last year and try to bisect to find the source of the regression. Thanks! cheers, josch --===============4901415456257742840== MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Description: signature Content-Type: application/pgp-signature; name="signature.asc"; charset="us-ascii" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJUsb8vAAoJEPLLpcePvYPhRDkP/3nq8SNabMVdXr6WQuE7SRV2 4ZehJ3IAM6uXIg9n4e8JCmWrWYrmwnOlz1O0vatXjyFgbizx2wUludiYMXUjblhS aHlxSOxa7fgN3ILGRCKPBUauE/BmT/N4kRXVBNKC9FgRjaiARuViq8gIZ+++aNdL rLnOiokvRQjdB2g9A7SMyMJXctR+SaCPHxQQLtgIUiDCCt6+lk8HCf91vVLHLSoo GU3wW83ClKz43d2voWjpr1jrEF5bI4lYGM5CEp++IFgRYz031knWGS5o4m+90k0b Ub0cmDrpSuZ9hQ3YUlGqlA54CNeRyDZtItUDMCeWee1hcqx/nwt5UWuzlmFa94+M b9o637Xhd15apimEwwSbtpGU41Jh5p1OS85kdkDqPxDFvlq0ipHDNBVl8yjRtRFY 3PBELzrQdSS+QAXUaZh9hlWZ5dGYNtrmHUbVZhk6QSdAjIydawaTGdzTaMcYd7Fe DpVx7C0EvImurIFNR5F2ubD6wlILpmJleZYQuGD6HD+nD/J+GoRRroHccvgNtAfh x8Nxi8v9RNe4XTg75xKQVcTMB68tfpFmLwdVmC+z4jz7UjbyeNQKaAKol9szXn3v t14asRbLZtvQHcOCV/UZ+bppzas86I/8TimDmDeQw29RC4H7fcHMEMnOYlDVEkG3 G6OiswJuL7fLKTbUXWYz =sFMM -----END PGP SIGNATURE----- --===============4901415456257742840==--
