MythTV Ignores LIRC Events for 2 minutes after startup

[mathew@…]

Summary

When MythTV Starts it ignores LIRC events for the first two minutes. After this time period, the remote works as expected.

Analysis

MythTV attempts to mount some devices on my system which eventually time out. While MythTV is doing this, it effectively blocks LIRC commands on the mythfrontend. This is the default behaviour of myth_system(). I have 4 of these devices (multimedia card readers) and on startup Myth attempts to mount these, each of which fails after 30 seconds, adding up to two minutes.

mount: can't find /dev/sdb in /etc/fstab or /etc/mtab

mount: can't find /dev/sdc in /etc/fstab or /etc/mtab
2010-01-10 12:05:48.465 Failed to mount /dev/sdc.
mount: can't find /dev/sdd in /etc/fstab or /etc/mtab
2010-01-10 12:06:18.582 Failed to mount /dev/sdd.
mount: can't find /dev/sde in /etc/fstab or /etc/mtab

Fix

I have patched my system by adding MYTH_SYSTEM_DONT_BLOCK_LIRC to myth_system() when called from libs/libmyth/mythmedia.cpp, and have attached my patch to the bug report. This causes the mount command to run, while not requiring mythfrontend to ignore LIRC commands.

(In [23314]) Fixes #7921. Don't block LIRC & JOYSTICK when mounting a file-system.

(In [23670]) Backport [23314] to -fixes. Don't block lirc or joystick input on startup when the media monitor is inspecting the connected media. Refs #7921
