The remote feels slow, not very responsive.
So, to investigate the issue, I loaded the ir-common module with
debug=1 and looked at the logs. They report lots of ir-common:
spurious timer_end. The funny thing is, I have tried the Ubuntu 10.04
i386 livecd (with the same kernel) and the problem is not present
there.

It is using the old RC support. This support will be removed soon, so, the
better is to convert it to use the new IR core, and fix a bug there, if is
there any.
Understood.
Please apply the attached patch (it is against my -git tree, but it will
probably
apply fine if you have a new kernel).
Applied, and indeed I was able to collect all the scancodes I needed :)
You should notice that the RC_MAP_ASUS_PC39 table is not ready for the new IR
infrastructure. So, you'll need to enable ir-core debug, and check what
scancodes are
detected there. Probably, all we need is to add the RC5 address to all codes
at the table.
Done.
Giorgio,
Based on the pastebin you posted via IRC, this is likely the patch you
need to also change your current keytable to work with the new RC core.
Thanks to your help on IRC, I fixed the keytable, new patch below.
Everything should work now, here's the log of my test:
