Linux kernel 3.5.0-20 won't boot [unable to handle kernel paging request at f91fe4fc in trace_event_raw_init+0xb/0x20]

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1087622

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I can't get to a terminal to execute this script.

This oops looks like the nasty; I can see a similar oops in bug 1087584 in the WiFiSyslog.txt around the 08:34 mark.

I hope it will help.

Behaviour here is a little bit different: 3.5.0-20 seems to boot and does display the log-on screen. However, the Ubuntu "drums" do not sound, and though the mouse pointer moves there is no reaction whatsoever on pressing a keyboard key or clicking a mouse button. I need to switch off the computer.
Going back to 3.5.0-19 worked on second try.
Could it be that something is hanging up when trying to play the drums sound? It's the first thing that does not work as usual.

I compared my dmesg logs from a failed start and a successful 3.5.0-19 start. The first 860 or so lines a pretty much identical (after removing time stamps) but then there are suspicious messages such as
* init: failsafe main process (794) killed by TERM signal
* Could not create debugfs 'i915_reg_rw' directory
* BUG: unable to handle kernel paging request at...
I am attaching the part of the file staring from the differing messages.

I get the same error. I get to the desktop because my laptop is configured to bypass the login screen, however I do not get wifi nor sound. I have got a Fujitsu LifeBook T730.

Kernel log of partly successful boot.

We believe we found the root cause and I've uploaded a test kernel that will fix the issue. You can download the test kernel here:

http://people.canonical.com/~henrix/lp1087622/

There are 2 versions, one for amd64 (64bits) and other for i386 (32bits). Please give it a try to see if it solves the problem and, if possible, report back with a dmesg. Remember to install, at least, the linux-image-* and the linux-image-extra-* packages. Thanks.

This version of the module fixed the problem for me.

The new kernel didn't resolve my issue. I'm running Linux Mint 14 (64-bit), and I haven't been able to boot since 3.5.0-17. I see a bunch of USB devices being recognized and then the system doesn't go any further. I'll troubleshoot later this afternoon to confirm whether it's really the same issue. I have a Lenovo Z580 notebook.

Scott, you're definitely seeing a different issue: this bug has been introduced in kernel 3.5.0-20.31. Please open another bug report. You can do this very easily from the command line, by running: 'ubuntu-bug linux'.

I tried to install the new kernel but software-center's progress bar stopped at about 95% and remained there for about 15 minutes, after which I closed it. It had not frozen, it reacted to closing and displayed the rotating progress arrows.

Today 3.5.0-20 effectively booted; I started the system and when I came back after dinner (~30 min) I was able to log on. I found that sound did not work but could run programs and download the proposed kernel (which did not complete installation).

When I shut down the system (to see if I still had a bootable state) I got the shut-down screen (blinking dots) for several minutes; I hit ESC and saw that the last message was "saving system clock to hardware clockhutting...". Probably a message written on top of another. As nothing seemed to change I switched off the computer and booted 3.5.0-19.

I tried to install the test kernel (i386) using the software center :
- headers installed smoothly
- image did crash the laptop : black screen with lots comments, hex numbers, and others things I don't understand. I had to hard reboot to 3.5.0-19.
I attached the dmesg file, hoping it can help.

The easiest way to install these test kernels is to manually download all the *.deb files into a directory. Then, in a terminal, just execute:

 $ cd <DIR-WITH-DEB-FILES>
 $ sudo dpkg -i *.deb

I tried to install them using dpkg instead of the software center. The system did not crash but the result's not really better :

5 minutes later, seeing that nothing was going to happen, I send a Ctrl+C, and here's what the process returned :

Thanks Luis.

3.5.0-20-generic #31+lp1087622v1 AMD64 works for me.

This bug is awaiting verification that the kernel for Quantal in -proposed solves the problem (3.5.0-21.32). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-quantal' to 'verification-done-quantal'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

3.5.0-21 works for me.

3.5.0-21-generic #32-Ubuntu seems working for me too. Had a similar problem before. Now it boots without problem.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

This bug was fixed in the package linux - 3.5.0-21.32
