I identified that this was blocking in the lirc init scripts on my system because of the file writes to /sys/class/rc/rc0/protocols file.

I don't know enough to troubleshoot further what it is that is causing this file write to hang. I also couldn't find any documentation with a brief google as to what this file actually does or why it is needed for lirc.

Changing the /etc/init.d/lirc script as follows stopped this behaviour.

#DISABLE_KERNEL_SUPPORT=true
DISABLE_KERNEL_SUPPORT=false

This caused no issues on my system, which is using both a USB DViCO IR receiver as well as an IR blaster. Ugly hack and would be interested to get more information on how to troubleshoot further to identify the root cause of the hang.

Re #3 above, this patch is already applied to the lirc drivers in the kernel so not required.
