Comment:

 The real issue causing the "deadlock" is that mythfrontend doesn't support
 suspend-to-RAM. I already knew that and had a suspend/wakeup script to
 restart the frontend. For other unrelated reasons, the restart script
 stopped working and hence the frontend wasn't restarted on wakeup. I never
 noticed as the frontend usually starts up before the TV is ready.

 Restarting the backend reestablished the connection with the frontend, but
 the real issue was the frontend being in an unconsistent state.

 The lack of logs on the backend was apparently also unrelated and was
 caused by a crashed mythlogserver:

 {{{
 mythlogserver[394]: segfault at 63 ip 0000000000000063 sp 00007f459904a678
 error 14 in mythlogserver[400000+3000]
 }}}

 I'll enable core dumps and post a separate ticket if mythlogserver crashes
 again.

 Sorry about the noise.
