When issuing a reboot from Ubuntu 12.04/12.10 (Linux kernel 3.5), the laptop hangs for about 1m30s on the "Restarting System" line of the shutdown output. This only happens when I have a second drive installed on the laptop (HDD, OS is installed in HDD). When removing the HDD restart progresses normally (no hangs, very fast). Said drive contains both the swap partition (4Gb) and a second ext4 partition, automounted on boot, manually set on
UUID=0240d6ae-722b-44ed-afad-865b1b3259c4 / ext4 errors=remount-ro,noatime,nodiratime,discard 0 1 UUID=025594dd-cd9f-4a9c-a078-88d69e4677ae none swap sw 0 0 none /tmp tmpfs nodev,nosuid,mode=1777 0 0 UUID=e9048353-e50c-4d7c-b716-9701bfdb4da9 /media/joao/DATA ext4 defaults 0 0
Unmounting the drive before reboot doesn't speed up anything, still hangs at the same step. The strange thing is, this only happens when issuing a restart, not when shutting down.
Anyone with any ideas/solutions?
