Whenever I start up a new Mathematica session, I have to restart the kernel do anything.

For example, if I just enter

1 (or any other command)

into a blank notebook, then Mathematica waits and waits and never returns an answer. It uses 100% CPU while doing so, getting stuck on the command (found using htop):

WolframKernel -wstp -mathlink -linkprotocol -SharedMemory -linkconnect -linkname -dnqwp_shm

To get Mathematica to respond, I have to restart the kernel via: Evaluation -> Quit Kernel -> Local and then Evaluation -> Start Kernel -> Local. After this, everything works normally.

My operating system is Linux (Arch), the version of Mathematica is 10.4, though I started noticing this problem earlier (around 10.2?).

I already tried Mathematica 10.0.x freezes in Initializing kernels, but it does not help (and in any case, the problem is not that Mathematica gets stuck at Initializing Kernels).

There seems to be a thread discussing this at: http://community.wolfram.com/groups/-/m/t/344133, but none of the steps help either.
