kernel panic, lenovo thinkpad x201

2 days ago I started getting kernel panics every half hour to two hours. These will happen whether the computer is being used or just idle (although Chromium is always open).

$ uname -a
Linux arch-satellite 3.12.2-1-ARCH #1 SMP PREEMPT Fri Nov 29 21:14:15 CET 2013 x86_64 GNU/Linux

Are there any logs I should post?

Look at the systemd journal and the X log.

Okay, in the systemd journal I see

BUG: unable to handle kernel NULL pointer dereference at 0000000000000018

Okay, after another panic, I see

dhcpcd: manage_link; No buffer space available

I see that a lot, but otherwise I don't see any errors in journalctl and there are no errors in xorg.log

Edit:
not sure if that is what's causing the panic, I highly doubt it is, but this thread talks about it. No resolution was found, and my connection is working fine

$ lspci | grep -i ethernet
00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06)
$ cat /proc/sys/net/core/wmem_*
212992
212992

Edit2:
if I turn on noapic I get a `drm_kms_helper panic occurred' on the panic screen.

Reverting to kernel 3.11.4 seems to have 'solved' it for now
