So getting back to this issue. It still happens with a relatively upstream kernel version 3.4-rc3. When experimenting a bit more it seems that there are various cases:
1. automatically mounted by udisk under /media and not having a shell changed into that mount dir. -> this seems to work, after resuming a new nautilus window appears as with a freshly inserted card 2. automatically mounted by udisk but having a shell changed into the mount dir. -> Shows the mount error, the mountpoint does _not_ show up in df or /proc/mounts and typing ls in the shell results in an IO error. 3. manually mounted (to /mnt) without shell changed into the mount dir. -> Shows the mount error, df and /proc/mounts do contain the mount point, typing ls results in the IO error. 4. manually mounted and changing into the mount dir seems the same as 3. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/913860 Title: Suepend/resume causes problems with mounted and active mmcblk device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/913860/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
