I've tested plugging in an SD card to an older laptop (also on hirsute). That is OK.
I've also noticed that the: mmc0: error -84 whilst initialising SD card message appears at boot time if the mmc card slot is empty. (the "mmc0: cannot verify signal voltage switch" message also appears on my old laptop, where things I working, so we can discount that). I'll gather the debug info now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1929444 Title: SD card initialization on insertion fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1929444/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
