My system is still freezing. I am working with 3.9.0-rc4 and using kernel option i915.reset=0. The system is rebooting after 10 minutes (in most cases). But maybe I have now some new interesting information:
I wrote a stupid script added into my crontab. The script is telling me every 3 minutes that everything is ok. I want to check if the system can log anything during the freeze. Now I have had a freeze at 11:17. The system reboots at 11:27. This is the syslog: You can see that my cronjob did not run at 11:15. The last entry was 11:09 and not 11:15 as expected. What are the jobs "anacron" and "cracklib" for? Can that be an issue?

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.
