Lenovo ThinkPad x260 dmesg

Looks like I have this very same problem on Lenovo ThinkPad x260. I attached my dmesg and it shows the same warning/trace. I'm running Fedora 24 with the latest updates and used powertop program to change the settings the program offers for better battery life (there was some problems with cpu/something related to it not going over some C2 state if not using powertop).

See also https://bugs.freedesktop.org/show_bug.cgi?id=95646, they are also trying to solve the same bug.

Comment 6 Hans de Goede 2016-07-12 16:46:48 UTC 
Also see:

https://bugs.freedesktop.org/show_bug.cgi?id=96214
https://bugzilla.kernel.org/show_bug.cgi?id=120451

And this is a potential fix:
https://patchwork.freedesktop.org/patch/97995/

I'm building a kernel to test this now.
Comment 7 Hans de Goede 2016-07-12 19:20:51 UTC

> I'm building a kernel to test this now.

Unfortunately the fix does not work.
Comment 8 Hans de Goede 2016-07-14 12:43:22 UTC 
Ok, I've attached a new fix to:
https://bugs.freedesktop.org/show_bug.cgi?id=96214

And I've build a test-kernel with this fix, which fixes things for me:
http://koji.fedoraproject.org/koji/taskinfo?taskID=14883873

If you want to test this kernel yourself, grab it while its hot, this is a scratch build so it will be removed in a couple of days.

p.s.

I'm going on vacation for the coming 2 weeks, so if I'm quiet that is why.

Comment 14 Jason Birch 2016-08-08 03:35:35 UTC 
I used to run into this one when connecting a DP 1.2 monitor to a USB 3 dock, which would result in a hard lock up.

On my system, using 4.6.5-300.fc24.x86_64 seems to push past these problems. While there's still a (different) panic, I no longer have a hard-lock of my system.

Thanks!
