 Posted: Thu Jan 01, 2009 1:10 pm Post subject: LIRC Issue when moving to 2.6.27-r7 [solved] |
 |
|
Hey there,
My gentoo system was stable until a couple days ago when I moved from 2.6.24-r3 to 2.6.27-7. I am guessing it might be related to some kernel config options.
When I boot up I get a message saying "udevd-event run_program /sbin/modprobe abnormal exit". The booting continues until the system attempts to load lirc_atiusb. It then hangs. Here are the snippets from dmesg:
| Code: |

I then booted into an old kernel and commented out lirc_dev and lirc_atiusb in /etc/modules.autoload.d/kernel-2.6. I was then able to boot into 2.6.27-r7. I then:
| Code: |
modprobe lirc_dev
modprobe lirc_atiusb
|
The system then freezes. I can Ctrl-C to break out of it.
Per http://www.gentoo-wiki.info/LIRC, I do have "Loadable module support->Module unloading" and "Device Drivers->Input device support->Event interface" enabled in my kernel config.
Any ideas?
Thanks
Mike

| I think you need lirc 0.8.4 for 2.6.27 kernel. |

Yup...just ran into this on my mythtv frontend. I had to add run the ~x86 lirc 0.8.4 in order to get lirc_serial to work. The odd thing was that with 0.8.3 lsmod showed lirc_serial as loaded even though I got errors about loading it, and lircd wouldn't start. Not sure what that was about.

guys, is there a possibility that if you use lirc on a laptop can you post your lspci?

I now do see the change comments for 0.8.4 lirc
| Code: |
*lirc-0.8.4 (12 Oct 2008)
12 Oct 2008; Matthias Schwarzott <zzam@gentoo.org>
+files/lirc-0.8.4-imon-pad2keys.patch, lirc-0.8.0-r8.ebuild,
+lirc-0.8.4.ebuild:
Version bumped. This adds Kernel 2.6.27 compatibility. Added driver
options irlink, commandir, ite8709 and samsung, Bug #221727. Removed
portaudio patch. Shorten description of lirc-0.8.0-r8.
|
I assumed it was a kernel config thing, my bust.
I did have lirc-0.8.3-r3 installed.
Added "app-misc/lirc ~amd64" to /etc/portage/packages.keywords since my systems is amd64 based.
Ran "emerge -av lirc" again which installed lirc-0.8.4 as expected.
Booted back into 2.6.27-r3 with my lirc modules commented out in /etc/modules.autoload.d/kernel-2.6.
Ran "module-rebuild rebuild"
Ran "modprobe lirc_dev" then "modprobe lirc_atiusb". No issues.
Reenabled lirc_dev and lirc_atiusb in /etc/modules.autoload.d/kernel-2.6.
Rebooted into 2.6.27-r3. No issues.
Thanks a bunch.
Mike
Sorry I am not using a laptop, since my system is a desktop also used for mythfrontend. |
