At every boot to
start Ubuntu, a partition gets re-mounted more than 1 times, sometimes causing very long boots. Example below:
> dmesg
...
[ 21.472020] EXT4-fs (sda5): re-mounted. Opts: errors=remount-ro
...
[ 42.021537] EXT4-fs (sda5): re-mounted. Opts: errors=remount-ro,commit=0
...
I suspect there is a problem of overlapping partitions here, regarding sda4 and sda5:
> sudo fdisk -l

I am Running Ubuntu Oneiric + LXDE on
Dell Studio XPS machine 64-bit, dual booting with Windows 7.
A months ago, I resized the Ubuntu partition and maybe I messed up something by doing that.
Do you have any idea, why this long booting is happening?
