[Bug 1302762] Re: gpartedbin crashed with SIGSEGV in _int_free()

[C. Jeffery Small]

Hardware: Asus U56E
Upgrade from Xubuntu 13.10 64-bit to 14.04 64-bit

I just upgraded to 14.04 and I also have this problem.  During the
upgrade, I received the above error multiple times.  Here is an excerpt
from /var/log/apt/term.log:

--------------------------------------------------------------------------------------------------------------------
Found memtest86+ image: /boot/memtest86+.bin
ERROR: unsupported sector size 4096 on /dev/sdb.
ERROR: unsupported sector size 4096 on /dev/sdb.
ERROR: unsupported sector size 4096 on /dev/sdb.

grub-probe: error: unknown filesystem
Found Windows Recovery Environment (loader) on /dev/sda1
Found Windows 7 (loader) on /dev/sda2
--------------------------------------------------------------------------------------------------------------------

/dev/sdb is an external USB-attached 3TB Seagate Backup Plus disk that
has been attached to 13.10 since it was upgrade, and has caused no
problems.

The upgrade acted as though there were unrecoverable errors and that the
upgrade would be backed out, but it continued and finished the upgrade
to 14.04.  There were a few minor configuration problems with the
upgrade, but it appear to work properly.  However, now, every time I
reboot, I get a blank screen with the message:

ERROR: unsupported sector size 4096 on /dev/sdb.

Then the system hangs for about 30 seconds or so before continuing with
the boot into xfce4.  Once up, the Thunar file manager sees the Seagate
disk and is able to mount and navigate it without problem.

The Seagate disk is being used as formatted from the factory.  gparted-
pkexec/gnome-disks show an initial 8.0/8.4Mb unallocated partition
followed by /dev/sdb1 with 2.73/3.0Tb NTFS filesystem and then another
unallocated 4.46/4.7Mb partition.

>From this information and the fact that this message is not logged in
any system file, I would assume the the problem is with the grub loader.

While this problem is investigated further, is there any way to stop the
boot delay when this message is displayed?
