RE: XPS 13 / Ubuntu 15.04 Freezes with Caps Lock Blnking

I am on bios 04 but I still get kernel panics once in a while (almost every day, but I close the lid, 3/4 times a day) 

Key repeats: YES still there, annoyingly, mostly with the space, so all my emails these days have two random spaces here and there. 

I don't use bluetooth much. 

Definitely some random trackpad jumping, when I am in gmail the email just disappear and I end up with a draft (at least it didn't send an email for me yet). 

I haven't seen the clock mode stuck, but it might have happened as well as sometimes the system feels slower.

So all of these posts are old and no solution from dell yet?

RE: XPS 13 / Ubuntu 15.04 Freezes with Caps Lock Blnking

Just to confirm, you have:

  1. Upgraded to kernel 3.19+
  2. Applied the patches from Dell (important to appy them AFTER upgrading kernel even though it says they are targeted for 3.13)
  3. Blacklisted mei and mei_me packages
  4. Replaced the wireless card or self-patched the Broadcom drivers to resolve null pointer issue

After these steps (in this order) you're system should no longer have key repeats or frequent kernel panics.  The wireless card will still not support channels 12 and 13 and bluetooth still isn't working (apparently).

I have done steps 1-3 and I don't have key repeats or kernel panics.  Since I haven't patched or replaced the wireless yet, I don't have channels 12/13, bluetooth, and I can get kernel panics once every month or two due to the null pointer issue...but I live in the US so the 12/13 channel issue is not usually an issue and the kernel panics aren't enough of a problem to demand immediate attention.

To the best of my knowledge, Dell Pro Support still haven't figured out how they want to handle these issues...so no, there is no ironclad solution from Dell yet.  Most of the fixes, workarounds and troubleshooting is still being done largely by the community (at least from my perspective).

For me, those steps fixed the kernel panics but not the keyboard. Nothing fixed the keyboard for me, and even the replacement laptop that Dell sent me also had the same keyboard problems.

BTW, replacing the Broadcom card with the Intel 7265 is the best solution to wireless & BT issues. Patching the Broadcom driver fixes the kernel panics, but doesn't make it work properly. Even after being patched, Bluetooth still didn't work after waking from suspend. The Intel 7265 works seamlessly with no need for driver installs or patches.

Nice to see you're still monitoring this forum MRC01!

Hmmm...I am a bit puzzled by the fact you are still getting keyboard repeats and I haven't had key repeat issues since I patched in the 3.19 kernel with the LTS testing repository back in February (before 3.19 kernel was available for 14.04 LTS).  In fact, I think you and I were going back and forth troubleshooting back then.

I have come a similar conclusion about replacing the Broadcom card.  I just haven't gotten around to it yet and I am waiting on Pro Support to approve the replacement so it won't void my warranty/Pro Support contract.

At the end of the day, I think I will just buy a Mac and install Linux onto it when I want to upgrade from this laptop.  The amount of troubleshooting and pain I have had to endure with this generation of the Sputnik has probably turned me off of Dell for a good while.

I can confirm that blacklisting the modules works as part of the solution.  Before that, closing the lid and opening it would send the laptop into a kernel panic (XPS 13 9394 A04 Ubuntu 15.04).  After putting in the blacklist and rebooting, I've tried closing the lid a few times and it seems to resume just fine.

I have this problem too, and also suspect it's a combo of suspend and wifi issues.


It's a total pain in the ***, causing me freezes ~10 times each day, and resulting in data loss all the while.


The problem only appeared recently for me,  probably within weeks. I've blacklisted the modules, have not patched the wifi drivers, and the issue still persists. Running Fedora 22.

RE: XPS 13 / Ubuntu 15.04 Freezes with Caps Lock Blnking

Hi,

You seem to be saying that you have not patched the wifi driver. This was key for me. These kernel panics stopped for me when I patched the Broadcom wifi driver (as described here: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1415880 )

I went from having one or two kernel panics a day to none since I did the patch (about one week). I also have the usually recommended modules blacklisted (i.e. adding blacklist mei, blacklist mei_me to /etc/modprobe.d/blacklist.conf.)

I have also set the XPS13 to do nothing on closing of the lid -- I just suspend via a press of the power button. However, I set this up before I patched the wife drivers (as I was mostly getting the panics when I closed the lid to suspend), and have not tried setting the lid close back to its normal suspend function...everything might be fine t now but I just have got into the habit of suspending via the power switch.

Good luck.

What worked the best for me to get rid of kernel panics was to swap out the Broadcom card with an Intel 7260NGW. I've only had two kernel panics since I got the machine, both times happened in the short window where I had the Broadcom card installed. I haven't had a single panic with Intel wireless cards installed. Plus, my Bluetooth now works.

I have patched the broadcom driver as described above, I have blacklisted mei and mei_me, I still suspend by closing the lid, and I have had no more kernel panics since patching the driver.

I also ended up replacing the Broadcom card with the Intel 7265, zero kernel panics since. I understand I could have patched the driver, but now I have a stable machine from the get go no matter which distro I choose to run..
