Hello,
I seem to recall this was a hardware fault in my case therefore for me it's
OK to close this bug.
Thanks,
John

John Lenton, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com

I believe my case is LP:539467 - the script for SATA ALPM config script
is back in Natty which modifies controller settings which does all that
i have described.

I'm getting somewhat similar crashes on my HP 6730b with Intel GMA
graphics. Crashes don't occur as often and I can safely say that they
happen on AC or battery power. I might go a couple of days
(realistically two - three max) without a hang. Besides problems with
random hangs, I do have problems
Hi, I don't really think the hangs in my case are caused by partition
remounting. I have pretty frequent system lock-ups (and then releases) while
being on the battery in Natty. I don't remember this behavior in Maverick and
no hardware change was introduced. My dmesg is filled by the following
Same for me on ASUS laptop + Maverick amd64 :
system hangs or freeze when deconnecting AC and going to battery mode
(No problems with pm-utils on Lucid)

So for me, the temporary solution pending the release of a patch,
Remove 3 maverick packages, and downgrade to Lucid versions :
acpi-support_0.136.1_amd64.deb
finger_0.17-13build1_amd64.deb
pm-utils_1.3.0-1ubuntu2_all.deb
(Need to block the version in Synaptic).
And no more freezes
Same thing here with on Dell Vostro 1015 with Intel graphics. Sometimes
it freezes after 5 minutes of usage if on battery. Turning on wireless
indeed seems to trigger the problem much more frequently.
I installed the 2.6.36 kernel from kernel-ppa, as well as the xorg
version from

on two vaio laptop with maverick fresh install (one with kernel 2.6.36
for another sound bug)
the file system is remounted after boot
one of the computer is new ,the other was with karmic and lucid without
this probleme (boot time longer on maverick than lucid or karmic)

I can confirm that my system actually has broken hardware, which could
well have been the cause of this issue for me (and perhaps others.) It
only showed up on a memtest running patterns - can someone else please
run a memtest overnight and see if they too have an issue?
I've been running win7
Unfortunately, my post of happiness (#21) was too early. Freezing is not
gone completely, however it now happens significantly less often. And I
suspect, that it happens only after the following sequence: putting my
laptop in suspend/hibernate state, come out of suspend/hibernate state,
then
You're right ivarsg, I had same issue with OS drivers.
Best workaround I found is downgrade to Lucid. Now I *really* can say no more
freezes.

On my laptop, I noticed that the boot time seemed a little on the long
side. When checking dmesg, I have also found that the file system
remounted after a boot. So far I have used my laptop only on mains, but
when disconnecting the mains, the same remount occurred as observed by
other people here.

I have similar behaviour - my system is freezing completely at random
moments, nothing suspicious in logs (or perhaps I don't know where and
what to look for).
However, I have the following observations:
- freezing happens only when running on battery, have not observed freezing
when on AC;
- it
Ok, can't reproduce it with ATI Open Source Driver (ati). Not a final
solution for me because OpenGL is broken with this driver (segmentation
fault) but it means Fglrx driver could be the cause of trouble. Anyone
is running with other than ATI fglrx propietary driver and has this
problem?

Well, my system freezing is gone.
I disabled ATI/AMD proprietary FGLRX graphics driver by pressing
Remove in System - Administration - Additional Drivers and rebooting
my laptop.
Now I am already some 3rd continues hour on battery at home using
wireless without any single freeze. Before it was a
Just to clarify: Re-mount logs only indicates commit change value
(from 0 to 600, from 600 to 0) to improve performance in laptop battery
mode. I deactivated this behaviour doing:
chmod -x /usr/lib/pm-utils/power.d/journal-commit
But my laptop still freezes. So I can confirm re-mount ext4 logs
Indeed I installed 2.6.36 from mainline, and kind of solved the issue, thanks

Same for me. When I plug/unplug the power cable my partition is
remounted. This is the exact message when unplug:
Nov 9 19:52:27 dalaran kernel: [ 9637.145067] EXT4-fs (sda5): re-
mounted. Opts: errors=remount-ro,commit=600
And this when plug:
Nov 9 19:52:29 dalaran kernel: [ 9639.158899]
Quite same behavior for me, but not sure if this is the same issue.

Overriding the commit option supplied in /etc/fstab doesn't look like a
