Further info I've just rebooted the laptop using the kernel that was left over from the upgrade from groovy. The mmc card reader works OK there.
A reboot back to the latest hirsute kernel has it failing again. So: 5.8.0-53-generic - mmc reader works 5.11.0-17-generic - mmc reader fails -- 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
