[arch-general] Lenovo carbon X1 and kernel 3.19 issues

[andrea crotti]

Hi guys,
I have a Lenovo Carbon X1 third generation, just bought a few months ago.

Everything worked perfectly but a week ago I upgraded to the new kernel
version:
"Linux carbon 3.19.2-1-ARCH #1 SMP PREEMPT Wed Mar 18 16:21:02 CET
2015 x86_64 GNU/Linux"

After that two problems started:

1. Audio doesn't work anymore, even speaker-test fails, I already tried
   everything and, the audio card still comes up, but nothing happens
   even using speaker-test, which makes me thing it might be a hardware
   issue, what do you think?

$ aplay -l

2. Sometimes after resuming from suspension Xorg becomes crazy.
   I use Awesome as VM and basically it still shows something but I
   can't click or do anything, and the weird thing is that if I kill
   "Awesome" and start it again, same problem.

   It only starts to work normally again when I reboot the machine.
   The problem is not Awesome either because I tried also Fluxbox and
   Xfce4 but still the same problem.

   I can't see any clue from the logs either, any idea what I could look
   at?


Thanks a lot


PS. About 1. sometimes while listening to music the computer would give
    a tiny shock that made the external monitor skip and a small shock
    in my headset, which was very annoying, and makes me thing is a
    hardware issue.
