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.
