Description Dionisus Torimens 2008-09-14 03:10:27 UTC 
Latest working kernel version: unknown
Distribution: Ubuntu
Hardware Environment: Acer Extensa 5220
Problem Description:
When I start my notebook from powered off, irdadump shows no responses to the queries. After booting XP and rebooting, irda works.

Steps to reproduce:
1. Power off completely.
2. Boot Linux.
3. Irda does not work.
4. Reboot into windows.
5. Reboot into Linux.
6. Irda works.

I will attach a diff of the output of lspci -vvxxxx before and after booting XP. I will also attach a diff of the dmesg outputs.

dmesg diff

The side-by-side diff between a boot before (right) and after(left) booting windows xp. I didn't find anything significant.

Same problem here:

kernel version: 2.6.27-7
Distribution: Ubuntu 8.10 "Intrepid" RC
Hardware Environment: Acer Travelmate 660

Latest working kernel version: 2.6.24-21 (Ubuntu 8.04 "Hardy")

I also use the nsc-ircc driver. But for me the described workaround didn't worked.
irdadump works normal but shows no response to IrDA devices:

Comment 4 Dionisus Torimens 2008-10-28 07:08:25 UTC 
Did IrDA work under Windows for you? Did you successfully use it there? Is it activated in your BIOS settings?
I haven't tried this in 2.6.27 yet.
Comment 5 Christoph Klaffl 2008-10-28 13:44:51 UTC 
Yes, IrDA works for me under Windows. I use it to transeive files from my mobile phone and so it is activated in the BIOS of course.

Have you tried these things

especially reducing the baud rate?

Yes, I just tried all the things described there without success.
