I started with 12.10 and later I upgrated to 10.40. I have also tested 12.04 32bit in the mean time (see comment #53) I think the kind of freezes were over all the time always the same. I am now running on Debian 7.1 which shows the same freeze with default kernel 3.2. So I updated yesterday to the kernel from the backports - version 3.10-0.bp0.2.
During my excursion to Debian I saw that there is a missing firmware (this was also logged under ubuntu but it did look to me that it was not a problem so I did not investigate into that. Debian complained about the missing firmeware when I try to install a kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/ , and forced me to uninstall it when I opened synaptic. So I was unable to install the kernels in a successful way. Now finally I succeeded with the backport version 3.10-0 by providing also the package firmware-iwlwifi_0.40_all.deb The system log looks now (for me) cleaner. I see messages like this: Sep 12 22:40:36 ralpus-ultrabook kernel: [ 1.763834] [drm] Initialized drm 1.1.0 20060810 Sep 12 22:40:36 ralpus-ultrabook kernel: [ 1.768513] cfg80211: Calling CRDA to update world regulatory domain Sep 12 22:40:36 ralpus-ultrabook kernel: [ 1.777166] Intel(R) Wireless WiFi driver for Linux, in-tree: Sep 12 22:40:36 ralpus-ultrabook kernel: [ 1.777169] Copyright(c) 2003-2013 Intel Corporation Sep 12 22:40:36 ralpus-ultrabook kernel: [ 1.781881] [drm] Memory usable by graphics device = 2048M Sep 12 22:40:36 ralpus-ultrabook kernel: [ 1.784463] iwlwifi 0000:01:00.0: firmware: agent loaded iwlwifi-2030-6.ucode into memory Sep 12 22:40:36 ralpus-ultrabook kernel: [ 1.784661] iwlwifi 0000:01:00.0: loaded firmware version 18.168.6.1 op_mode iwldvm Sep 12 22:40:36 ralpus-ultrabook kernel: [ 1.802459] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).

When the system freezes no mouse , no keyboard, no REISUB is possible. The screen is corrupted and did not update. The only key board functionality which is still possible is Fn+F9 (switch display on/off). I need to switch off the system hard. The freeze occurs when the system runs on battery as also when it is plugged. When the system freeze occurs with power adapter plugged the system switches off when I disconnect the power adapter - even if the battery is full charged. But the powermanagement in general seems to work perfect in Ubuntu 12.10. To me it looks like the system freeze occurs often after high memory usage. I can use the system with a few applications (Thunderbird / Firefox) for long time (several hours) without any freeze. But when I start java programming the probability increases that the problem occurs. This means: I start Eclipse 4.2, MySQL and GlassFish 3.2 Server. I open a lot of browser windows and read and write much files to disk. The memory usage in this case increases from less then 1GB to more than 3GB (on total 8GB Ram) - I do not know if this is relevant - but maybe. I observe the situation for more than two months. As I use my system for work I have freezes one or two times a day - mostly when I have much work ;-) I develop JEE server business applications - so in the situation when the system freezes there is really no heavy graphic load. I am using Gnome Shell. The freeze seems to be absolutely randomly - I can not reproduce the system freeze. I can not be sure but it seems to me that since yesterday the system shuts down after some seconds when it feezes. I notice this because I tried to login via ssh to collect the data of the file /sys/kernel/debug/dri/0/i915_error_state. But as the system shuts down I was not able to check the content. --- ApportVersion: 2.9.2-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu 4258 F.... pulseaudio ubuntu 14314 F.... pulseaudio CasperVersion: 1.331 DistroRelease: Ubuntu 13.04 LiveMediaBuild: Ubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) MachineType: To be filled by O.E.M.
