Adding some debug info, shows that the mount problem (which is /proc/fs/ext4/mmcblk0p1, /proc/fs/jbd2/mmcblk0p1-8, /sys/ext4/mmcblkdp1 and an internal kobject named mmcblk0p1 trying to get created while they still exist) at least is made worse by the fact that ext4 seems to create /sys and /proc entries when a block device is accessed.
So on the way to suspend, at least mmc_remove_card() gets called (as it is intended to protect against cards being changed). This removes the card from the mmc bus and causes mmc_blk_remove() to be called. This in turn calls mmc_blk_remove_req() for each partition and the main device and that theoretically would call del_gendisk() (but only if GENHD_FL_UP is set). So next step is to try to find out whether this is true or not... -- 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
