I failed to reproduce this bug this morning while filling a report to upstream. I'm positive yesterday all tested kernel had the same problem. But now, my card reader is working again on both kernels. I restarted quite a few times to be sure it wasn't some kind of random error during boot or something similar.
My best bet is that it's an hardware failure of some sort. I'm very surprised, since the bug appeared just after the fresh install and stayed across multiple reboots. Anyway, sorry for the trouble and thank you for your help. ** Changed in: linux (Ubuntu) Status: Triaged => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/992398 Title: Integrated SD card reader cannot initialise card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/992398/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
