"Corrupted low memory at" kernel warning on resume

[Erno Kuusela]

I just noticed these. Each time happened on resume from suspend to ram, but it doesn't happen after every suspend/resume. Hardware is ThinkPad X200s, running Jaunty/AMD64.

Hi,

I am having the exact same error message whenever my computer boots. I have a Lenovo Ideapad y530 2PU. Dmidecode also tells me that I have 667 ddr2 ram when I actually have 1066 ddr3 ram. Please check this bug report which I poasted:

https://bugs.launchpad.net/ubuntu/+bug/368873

[Scott Testerman (scott-testerman)]

This is still happening in the 2.6.28-13 kernel.

[Aliov (aliov)]

Similar problem on ACER aspire 5710, please fix it.

[meatlover (davisds)]

Still happening for me since the kernel update

[Eddie Hung (eddieh)]

I'm seeing this with the latest Karmic, on an Intel DG45FC board too, when resuming (though not always reproducible). What are the symptoms everyone is reporting with this issue? For me it's possibly related to compiz going haywire: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/421900

[Eddie Hung (eddieh)]

This thread reports that users of the 2.6.30 kernel with 9.04 are seeing good reuslts: http://communities.intel.com/message/63790

- with kernel 2.9.30.5 suspend works fine, it works with and without the acpi=rsdt trick.
- with kernel 2.9.29.6 suspend only works when acpi=rsdt is specified
- with kernel 2.9.28-15 suspend does not work, not even with acpi=rsdt ...

[Solitaire (bill-s0l)]

I've just started getting a similar error:
Suspend to ram and resuming from ram are fine.
I just get the error when i restart my machine (triple boot between Win7rc, 9:10 A-6 and 9:04)

[UbuntuJohn (jdrago-999)]

I have the same problem - Lenovo Y530 with Dual-Core Intel Centrino and Ubuntu 9.10

8.10 worked fine, and 9.04 did too. After installing 9.10 it started getting flaky - would be fine for a little while then it would freeze up. After rebooting, it would go into a never-ending reboot cycle.

Sometimes it would reboot right after I made a boot selection in GRUB. Sometimes it would reboot before the login screen would appear. Sometimes it would reboot after the login screed appeared and I logged in, but before the desktop would appear.

I have run memtest (or memcheck86+ or whatever it is) - both by pressing "F2" on bootup and the one installed with Ubuntu (presumably - not sure if there's a difference). Memtest never found anything wrong.

I also though maybe it was a hard drive problem so I just installed a new 7200 RPM 360GB Hitachi, installed 9.10 and the same thing happens. Except now I'm lucky if I make it to the glowing white Ubuntu icon. Most of the time it dies right after I make a selection in GRUB.

I have tried the "recovery mode" option in GRUB. I see a lot of text scroll past the screen and then it goes black - just before the computer reboots.

I'm currently downloading 10.04 to see what happens...maybe it doesn't suffer from the same issue?

I'll post here again with my results this afternoon.

Best,
Drago

P.S. - To all the Ubuntu/Debian hackers out there - THANK YOU THANK YOU THANK YOU THANK YOU!!!!!

[UbuntuJohn (jdrago-999)]

OK - I downloaded the Lucid Lynx development ISO (32-bit) and installed it - works great!

my uname -rv looks like this:

2.6.32-4-generic #5-Ubuntu SMP Fri Nov 13 13:38:07 UTC 2009

BTW - Skype 2.1 beta works great too.

[Bernie Bernstein (bernie9998)]

I have since been able to work around this issue without having to move to the development lucid lynx distro. Instead, I found a 2.6.32 kernel build in this ppa repository for karmic:
https://launchpad.net/~apw/+archive/green

I added this ppa to my sources list and apt-get installed linux-image. Since upgrading the kernel, I no longer get this corrupted low memory error and my laptop appears to be stable again.

[meatlover (davisds)]

@Bernie: I'm running Jaunty, will updating my kernel to 2.6.32 cause any stability issues?

[Bernie Bernstein (bernie9998)]

I've never tried the 2.6.32 kernel with Jaunty. I never had any issues with the stock kernel included with Jaunty, so I never upgraded it.

The kernel itself appears fine with my hardware. I don't think there would be issues with the newer kernel running on the Jaunty release, but I can't say with certainty as I never tried it.

[meatlover (davisds)]

@Bernie: I've updated to karmic. After updating to 2.6.32, is there any way I could revert back in case I encounter any problems? Also, has suspend started working for you since the update?

[Sam Briesemeister (sam-briesemeister)]

Hi all - I installed Karmic in November and only now noticed this problem.

My hardware: an IBM ThinkPad R5. (See attached lshw output for more details.)

I haven't identified a specific cause. To trigger the problem, I can start either Armagetron or Chromium, and soon files all over the place become inaccessible.

Initially I thought it was just an ext4 problem, since I was observing filesystem corruption issues (or so I thought). After converting completely to ext3, I still see weird FS issues (it now thinks my 8gb / partition is 16T and 100% full).

Finally I looked to dmesg, which posted the same "low memory corruption" message.

[Sam Briesemeister (sam-briesemeister)]

Two typo's:

It's an IBM ThinkPad R51.

Chromium BSU (the space shooter game) seems to trigger the issue on my system.

[Thorkhas (jc-opencoin)]

I have the same kernel message issue.

I'm on a laptop IBM T40p (yes I know, it's old) running Karmic and kernel 2.6.31-17-generic

The issue arises when I start a 3D-heavy game using wine.

Here are the kernel messages :

[Mark Mandel (mark-mandel)]

I am also getting this bug on my laptop (Alienware m17x).

This happens to me randomly on boot, and randomly when resumed from suspend.

This happens pretty much very time I pull my power cable out from the back of my laptop (which is where I got the attached dmesg.log file from). Quite often if I pull out the cable from the back of my laptop, I will actually get a kernel panic, but not every time.

Let me know if I can provide any more details.

[Brian Rogers (brog45)]

This started on my mother-in-law's laptop when she upgraded from 9.04 to 9.10. Laptop is a Compaq Evo N800v. Seems to be triggered by suspend/resume or heavy video usage. A reboot tends to find the filesystem corrupted. A coupe of days ago, I had to rescue the contents of the /home directory from lost+found!

[Brian Rogers (brog45)]

Does anybody know if the recent kernel update fixed this? I couldn't wait for a fix and had to backup the /home directory, reformat, reinstall 9.04, and restore /home.

[Mikhail Titov (mtitov)]

I've got this warning on Lucid Lynx with 2.6.34-020634rc7-generic kernel upon resume from ram-suspend.

[Stuart (stuartneilson)]

I have this on the same mainline kernel (2.6.34-020634-generic #020634), is this a regression, and is it something that can be ignored or is it harmful?

Erno,
   Please send me the dmidecode info for your machine that is experiencing this. There is a quirk needed it appears.

Stuart,
   Please open a new bug for your issue using 'ubuntu-bug linux'. This should provide me what I need for the fix.

Thanks!

ubuntu-bug does not complete with a mainline kernel.

What can I add here that would help?

[Jeremy Foshee (jeremyfoshee)]

Stuart,
   You will need to boot into the original kernel by holding the shiftkey during the grub boot to bring up the menu.

You have not explained why there is any benefit in booting into an old kernel (which does not exhibit this bug) in order to report a duplicate of this bug.

If there is any information that is useful to the resolution of this bug, then please let me know what to post and I will post it here.

I have a related problem. Almost everytime I leave my computer for awhile and come back, it won't turn on and it's frozen. I checked the logs and it's low level memory corruption. This problem has been happening every since I got Lucid... And there appears to be 0 problems in Windows 7. No idea why this is happening, but my system is crashing WAY TOO MUCH, and it's very annoying having to recover the file system on a daily basis because of this.

Can you please test and report if this works?

memory_corruption_check_size=128K

in the boot options.

The default is

memory_corruption_check_size=64K

but it seems that's not enough for some systems.

Thanks

If you don't know how to set BootOptions read

Also this thread is very important to anyone looking at this bug

I have this same issue while booting a 10.10 live cd. Setting the memory_corruption_check_size to 128K allowed the system to boot but it had stability issues (applications were crashing, GUI icons were corrupted). Setting it to 256K appears to be stable, I am currently installing the system and have not run into any problems yet.

I can't paste my whole dmidecode at the moment, but here is some of it:
SMBIOS 2.3 present
vendor: intel
Version:AG91510J.15A.0579.2004.1008.1003
Runtime size: 64k
Rom size: 512k

Had the same problem on an HP ZBook 15u G2 and Ubuntu 14.04 (Linux 3.16.0-31-generic).

Since HP is officially offering this computer with Ubuntu preinstalled, I imagine that they are going to fix this with a future BIOS update (the notebook just got newly introduces).

For now passing memory_corruption_check_size=128K appears to avoid the issue. Thanks @nutznboltz for the tip!
