libftdi was updated recently, with abi changes but no soname bump, resulting in breaking a few other apps that use libftdi. I suspect that's what happened here, and lirc-0.8.6-6.fc13 should remedy the problem, once I actually tell it to build...

lirc-0.8.6-6.fc13 has been submitted as an update for Fedora 13.

Also don't forget a build in rawhide/F-14 for a clean upgrade path, currently devel/ branch is 0.8.6-4 < 0.8.6-6 (F-13 branch).

lirc-0.8.6-6.fc13 has been pushed to the Fedora 13 testing repository.  If problems still persist, please make note of it in this bug report.
 If you want to test the update, you can install it with 
 su -c 'yum --enablerepo=updates-testing update lirc'.  You can provide feedback for this update here: http://admin.fedoraproject.org/updates/lirc-0.8.6-6.fc13

*** Bug 572843 has been marked as a duplicate of this bug. ***

*** Bug 585796 has been marked as a duplicate of this bug. ***

As per bug 585796 this still happens with
lirc-0.8.6-6.fc13.x86_64
libftdi-0.17-3.fc13.x86_64
kernel-2.6.33.2-57.fc13.x86_64

It's quite reproducable (every time I boot my mytv frontend). When started by /etc/init.d/lirc then lircd fails to open the USB IR device every time. When the lircd command run from that script is started manually by root then it fails the first time and works the second time. Disabling selinux didn't help. This was fine on prior Fedora, breaks on F13.

Relevant lines from syslog showing the three start attempts. Note there is also a kerneloops (reported) on boot that might be part of the problem.

Damn. Well, I've got usb-uirt hardware around here somewhere, I'll dig it out and hook it up to one of my F13 boxes and see what I can see.

I'm having this exact same issue. Anything I can provide to help fix it?

This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '13'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 13's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 13 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
