           Summary: hibernations problems: ext4 errors after some
                    hibernation cycles
           Product: File System
           Version: 2.5
    Kernel Version: 2.7.1
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext4
        AssignedTo: fs_ext4@kernel-bugs.osdl.org
        ReportedBy: higuita@gmx.net
        Regression: No


i'm using a ext4 root partition on my slackware64 and i regularly hibernate the
machine. After some hibernation cycles i usually get the root partition mounted
as read-only. Strangely, my home partition, also ext4 its always fine.

After the reboot and fsck and some minor corrections (mostly freeing unused
blocks, after all the /tmp is on the root partition) all works fine.

i'm getting this on mainline kernel 2.7.1 but i have this for several months
(more than six at least), time where i started to use the hibernation.

The problem is hard to reproduce, i get it some times with 2-3 hibernation,
other after many hibernation cycles or don't get it at all.

i don't know if its related, but if i force enable HPET on my machine, the
system works well, but after hibernate the many process act strangely,
specially related with X11. Due to this i stop forcing the HPET, but this
incident turned me more alert for small problems. I start to note that my xterm
are sometime slower rendering the text after hibernating the machine. On a
normal powerup the xterms work fine.

This may or may not be related, the main problem is still the ext4 corruption.
