New: Resume from hibernate corrupts ext4
https://bugzilla.kernel.org/show_bug.cgi?id=16019
Summary: Resume from hibernate corrupts ext4
Product: Power Management
Version: 2.5
Kernel Version: 2.6.33.4-95
Platform: All
OS/Version: Linux
Tree: Fedora
Status: NEW
Severity: high
Priority: P1
Component: Hibernation/Suspend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Regression: No
Overview: System appears to hibernate successfully. Upon resume at first sight all seems well until one discovers it is no longer possible to write to disk.
Steps to reproduce:
1) Hibernate system to disk. (Note suspend to ram seems to work ok).
2) Resume from disk.
3) System starts up ok, but disk seems to be mounted read only. Sometimes resume just fails and system auto reboots itself and fixes the ext4 disk errors.
4) Rebooting seems to fix the disk issues.
Expected result:
Resume from hibernate should work ok.
System info: Fedora 13 kernel 2.6.33.4-95.fc13.x86_64 Dell Latitude D630, 2G ram, 4G swap
Attached log messages from suspend/resume cycle.
First ext4 error is
May 20 06:28:41 trillian kernel: EXT4-fs error (device dm-0): ext4_mb_generate_buddy: EXT4-fs: group 26: 1161 blocks in bitmap, 1149 in gd May 20 06:28:41 trillian kernel: JBD: Spotted dirty metadata buffer (dev =

then it ends with lots of

Is this reliably reproducible? It looks like a block allocation is getting corrupted when you hibernate.
What are you using as your hibernation partition?
The disk is a
ATA toshiba mk6037gsx (sata harddrive) set up as a lvm2 volume (28Gb) partitioned as 24 Gb ext4 plus 4 Gb swap
As far as I know, the swap is the hibernate partition. Am using pm-hibernate or standard gnome tools to hibernate.
The problem happens every time I hibernate. Let me know what other info would be useful.

--- Comment #6 from Eric Sandeen <[email protected]> 2010-05-21 17:10:58 --- Just to test a theory, could you try doing "hdparm -W" on your disk(s) to check the write cache status?
If it's 1 (on), then prior to hibernate, can you try hdparm -W 0 on the disk(s) and see if the problem persists? I'm wondering if it's possible that data in the drive's write cache got lost when the system powered down, if it wasn't properly flushed during hibernate.
You'll want to do hdparm -W 1 later to turn them back on if that was the original state.
Thanks,
-Eric

I gave that a try and did not find any difference.
The original state was 1 (on) so I set it to 0 and did a hibernate. The system comes back up with the unwritable disk as before.

I tried kernel 2.6.33.4-106.fc13.x86_64 and no longer get the warning.
However the ext4 errors are back with a vengeance -- auto fsck on reboot now fails and a manual fsck is needed to repair the disk.
--- Comment #15 from Eric Sandeen <[email protected]> 2010-05-22 17:03:03 --- Testing on F13 in an x86 guest with pm-hibernate from runlevel 3 doesn't trip up the error, so it's not something blindingly stupid/obvious/reproducible ...

Back in Fedora 11 everything was working fine. With Fedora 12 so many things regressed at the same time that testing was impractical (I think mostly intel stack related...). I think suspend to ram worked fine, and hibernation would just freeze. However with Fedora 13 I am really just left with this one problem, hibernation.
iommu=soft gave me one clean hibernation from inside gnome, but the second attempt gave me the same ext4-fs errors

--- Comment #19 from David Lowe <[email protected]> 2010-05-28 23:03:31 --- I switched over to Ubuntu 10.04 and no longer have problems with hibernate or suspend. I also tested this against the vanilla 2.6.33.4 kernel under ubuntu, without issue.
The main differences seem to be:
(1) I am no longer using an lvm2 volume with an ext4 partition, just a simple extended partition with ext4
(2) fedora patches to the kernel
(3) fedora/ubuntu differences in pm-utils, if any

came here from "my" fedora bugzilla
(https://bugzilla.redhat.com/show_bug.cgi?id=603897) I found this bug. I'm having it on an Aspire One with SSD. Guess the lvm theory is very reasonable. If I can spare the time I'll try the alternate install this weekend. Btw, I also got the following messages:
ERROR: sil: invalid metadata checksum in area 3 on /dev/dm-1
ERROR: sil: invalid metadata checksum in area 4 on /dev/dm-1
with /dev/dm-1 being the swap partition.

You might try unloading/blacklisting i915 and test hibernate again, either from plain VGA X, or a text console, see if it makes a difference. (I don't know if ubuntu has a different i915 driver... feel free to test the lvm theory too!)

just did some tests with a clean initrd without i915. No fs corruption. While as soon as the i915 module is in use I get reliable fs corruption. So. Guess the lvm theory is dead... It's the i915 module

David, are you certain that you can hit it without i915 loaded? If so then there is more to track down.

--- Comment #37 from Klaus Lichtenwalder <[email protected]> 2010-06-18 14:52:04 --- In my case it's a Fedora 13 32bit kernel. Just for completeness I attached the config (Comment 36).

--- Comment #38 from Klaus Lichtenwalder <[email protected]> 2010-07-01 05:04:30 --- I don'r know whether this is related, but one in a while I have a lockup of the X server. I can move the mouse, and switch to the tty consoles, and log in, but for a working X I have to reboot. Yesterday I saw in dmesg:
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung render error detected, EIR: 0x00000000
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 302900 at 302900)

--- Comment #40 from Steven Bakker <[email protected]> 2010-07-27 20:37:22 --- I'm running 2.6.33.6-147.fc13.x86_64 with an i915, and unfortunately, it still corrupts the ext4 FS on hibernate/wakeup.
(Off-topic: I'd be happy for my laptop to just auto-suspend when it's running on battery, but that doesn't seem to be configurable: it's hibernate or nothing.)

--- Comment #44 from Klaus Lichtenwalder <[email protected]> 2011-02-15 15:31:10 --- Hi,
running 2.6.37-2.fc15.i686 works fine, but using rawhide kernel-2.6.38-0.rc4.git0.2.fc15.i686 or kernel-2.6.38-0.rc3.git0.1.fc15.i686 shows errors very fast! Even faster than in 2.6.35... Most of the time in /sys...

--- Comment #45 from Klaus Lichtenwalder <[email protected]> 2011-03-21 15:04:18 --- Still the only kernel working is the one from comment #44. I tried the kernel from fc15 alpha, kernel-2.6.38-1.fc15, but no cigar. At most two resumes, then I get a kernel oops, with dentry_* on top. I can try to manually get a trace, if this helps.

can you please verify if the problem still exists in the latest upstream kernel?
