I'm also affected by this on Ubuntu/precise (Mint/maya). I have my internal laptop drive with dual boot HFS+/Mac OS X and ext4/GNU/Linux. The grub-mount hang never happens with that disk. It does happen when my external backup disk is attached. I thought maybe it had something to do with how the disks were partitioned. Here's my internal disk that works fine:
$ sudo parted /dev/sda GNU Parted 2.3 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: ATA ST9750420AS (scsi) Disk /dev/sda: 750GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 20.5kB 210MB 210MB fat32 EFI System Partition boot 2 210MB 483GB 483GB hfs+ Untitled 3 484GB 645GB 161GB ext4 Untitled 4 645GB 666GB 21.5GB ext3 Apple_HFSX_Untitled_4 5 666GB 750GB 83.8GB ext3 Apple_HFSX_Untitled_2 Here's the backup disk that triggers the problem: $ sudo parted /dev/sdb GNU Parted 2.3 Using /dev/sdb Welcome to GNU Parted!
