Arch Linux

Description:
In kernel version 3.4.7-1-ARCH (current at the time of this writing) and a few others before it, my IR receiver has stopped working. I see no output from my remote when using ir-keytable -t, all configurations look right and there are no errors in dmesg or ir-keytable. However it works with kernel version 3.0-ARCH (the one included with the archlinux-2011.08.19-core-x86_64 iso). I installed that kernel along side the current one in my computer and the IR receiver works again when using the old kernel.

Additional info:

* package version(s)
Kernel 3.4.7-1-ARCH (not working)
Kernel 3.0-ARCH (working)


* config and/or log files etc.

Laptop model: MSI GX620
Remote controller: Harmony 300 (configured as MCE remote)
