rtl8192ce kernel panic on bootup

[Jure Sah]

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.4 LTS"
Fully updated.

Linux 3.8.0-37-generic AMD64 kernel, the rtl8192ce driver sometimes causes a kernel panic on system startup of my Lenovo Thinkpad X230. Restarting many times results in some sucessful boots, but the problem can be persistant. The problem does not occur on the Linux 3.8.0-36-generic AMD64 kernel.

Unfortunately the dump I get on the screen durring such crashed boots, does not appear to be in the logs.

Can you see if this issue also happens with the latest 3.8 upstream stable kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.19-raring/

[Brad Figg (brad-figg)]

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

apport-collect 1289429

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'm having this same problem with the same symptoms on the x230. Also crashes on 3.8.0-38. Going back to 3.8.0-36 works.

[Steve Sether (stevesether)]

I should also add if I turn off the wireless, the machine boots. As soon as I turn on the wireless, kernel panic. I managed a screenshot taken with my phone. It's mostly legible.

[Domu (rj45rt)]

I used Ubuntu 12.04LTS. I have met the same problem. the Kernel version is 3.5.0-48-generic. I rolled back to 3.5.0-47-generic. It has the same problem. But the problem disappeared when I rolled back to 3.5.0-46-generic. So I guess it is due to kernel upgrade.
btw, I also used rtl8192ce driver.

[Steve Sether (stevesether)]

Is anything going to happen on this bug? The x230 is supposed to be "certified" on Ubuntu, which is the reason I bought it. Now it's crashing on the latest kernel release but I've heard nothing for 2 weeks.

[Jure Sah (dustwolfy)]

I believe they need us to, and I quote "see if this issue also happens with the latest 3.8 upstream stable kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.19-raring/", something I have been getting around to trying for the aforementioned 2 weeks, however if you beat me to it it will be faster. :)

[Jure Sah (dustwolfy)]

I have succesfully reproduced the problem on the linux-image-3.8.13-03081319-generic kernel from the link provided. I should mention that initially the problem did not occur on either reboot or poweroff and boot, however after I powered down the laptop, removed the battery for a few seconds and then powered it back on, the problem occured with 100% reproducability.

I attach the screen-shots of the debugging output (which does not get entered into the logs), from my testing.

[Jure Sah (dustwolfy)]

Another screen-shot, same kernel, slightly different circumstances.

[Jure Sah (dustwolfy)]

I would like to mention that, when the computer is booted off with the wifi killswitch OFF the machine boots normally as vellmont mentions... Running dmesg -E on a bare console (ctrl+alt+f1) at this point and then turning on the wireless produces a ton of output when it crashes... Perhaps there would be some way to capture this output?

[Zhu Lihua (zhulihua365)]

I have exitly the same problem, beside my laptop is lenovo T430.

Now works well after I go back to 3.8.0-36-generic.

[Matthew Runo (matthew-runo)]

Also happening for me, -36 works, nothing newer than that does. If I boot without networking it works, then crashes as soon as I enable networking.

[Nick Sukharev (nicksukharev)]

Happens to me as well, -37 seems to work -38 and -39 do not. I also have Lenovo laptop X230

[Tim Gardner (timg-tpi)]

Joe - I received email from the driver maintainer (Larry Finger) with a patch. Please build a test kernel and submit for testing.

"Sven and Tim,

Attached is a one-line fix for the problem that shows up between 3.8.0-36 and 3.8.0-37. It is just a bare patch file, but feel free to add any explanatory text to make it a proper commit.

I have no real understanding as to why this line of code does not cause any problems with later kernel versions, but it does here. In addition, I have not had any reports of problems with other users. That makes me suspect some kind of bad interaction with the user-space network control components in 12.04.

Would it be helpful for Nicolas to prepare a bug report at Ubuntu?

Larry "

[Tim Gardner (timg-tpi)]

Joe - it appears that this bug is also happening in 3.5. From Larry Finger:

"Tim,

I agree that #1289429 is this bug. It seems that the problem also happens for 3.5.0-48-generic. If that is being supported, it also needs this patch.

Larry"

[Joseph Salisbury (jsalisbury)]

I built a test kernel with the patch from comment #14. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1289429/

Can folks affected by this bug, test this kernel and post back?

[Steve Sether (stevesether)]

Running the -40 kernel right now with no issues. Previously in locked up right away. I turned off the wireless and turned it back on again with no issues.

Looks like this is fixed.

[Matthew Runo (matthew-runo)]

I downloaded and installed the -40 kernel, and my x230 now boots just fine.

Looks fixed.

Thank you!!!

[Arne Pisch (oldman999)]

Also here on HP 4530s. :)

[Arne Pisch (oldman999)]

3.8.41 seems ok but 3.2.63 only with backports 3.12 cw modules, crashes otherwise.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
