Public bug reported:

Looks like it's when it's trying to read from a socket, from what I can tell?

If it's ptrace'd (IE, ltrace -p $PID or strace -p $PID) then it will
resume.

However, please note that I am using an Intel chip that has builtin AES
instructions, this may be related to a firmware/hardware issue rather
than a specific problem with the software package.
