I was about to file a bug repoort when I came upon this one:
https://bugs.archlinux.org/task/55629?string=kernel&project=1&type[0]=&
sev[0]=&pri[0]=&due[0]=&reported[0]=&cat[0]=&status[0]=open&percent[0]=
&opened=&dev=&closed=&duedatefrom=&duedateto=&changedfrom=&changedto=&o
penedfrom=&openedto=&closedfrom=&closedto=

So looks as if it's related to i915 video driver (at least for me)
since the proposed workaround to add intel_iommu=igfx_off to
/etc/default/grub works for me.
