            Bug ID: 111961
           Summary: ext4 umount - invalid opcode with PLEXTOR

            Status: NEW
          Severity: high
          Priority: P1
         Component: ext4

journald

On shutdown system hangs and prints stack trace. After reboot I had to recover
my home partition with fsck, sector count was corrupted (didn't check on data
loss yet). I've attached journald log + hdd info.

My partitions are mounted with defaults + noatime flags. The ssd is tied to an
acer chromebook 11 C740 running arch linux (no Chromeos).

If you need any more info don't hesitate to ask.

best regards


Sebastian
