I am sorry guys, bad news: this last update freezes when starting irda.

[Dennis Kaarsemaker (dennis)]

Which card and driver?

[Adriaan Peeters (apeeters)]

I included that information in the bug report:

> My machine is a Dell Latitude D505 with the i810 driver on a 82852/855GM.

Please let me know if you need more information.

[Dennis Kaarsemaker (dennis)]

Oops, missed that. Could you try vesa please.

[Adriaan Peeters (apeeters)]

By changing to vesa I noticed a kernel dump which indicates a problem with irda. When I started /etc/init.d/irda-utils manually in single user mode, the system crashed again about one second after running the command.

kernel_trace of irda problem

[Adriaan Peeters (apeeters)]

This is probably related to bug #41589

[Jede28 (news-saring)]

Hi,

I can report the same problem with the latest Dapper install. I have a Dell Latitude D620 with Centrino Duo, IPW3945 and Intel GMA 950.
Since I updated to kernel 2.6.15-23 the kernel very often (not always) freezes on booting. It happens during the GDM is beeing started. No chance to change to console. After rebooting the old kernel I was not able to find any informations about the problem in the logs.
I've checked the bug list and found this one. So I disabled IRDA in the BIOS and now it doesn't crashes on boot anymore. So this workaround seems to work for now, but without IRDA ...

HTH, Eddie

[joe (joerg-unglaub)]

I can confirm this issue same trace of kernel for kirdaD
And X locks up before loginscreen

if it helps Hardware is here

[joe (joerg-unglaub)]

Ok blacklistet IRDA a et voila system works but therefore no irda-support....

[Philip Axer (phaxer-merged)]

Hi,
in drivers/net/irda/sir_kthread.c line 133:

                 prepare_to_wait(&irda_rq_queue.kick, &wait, TASK_INTERRUPTIBLE);
                 if (list_empty(&irda_rq_queue.request_list))
                        schedule_timeout(HZ/10);
                else
                        __set_task_state(current, TASK_RUNNING);
                finish_wait(&irda_rq_queue.kick, &wait);

I'm not a kernel expert, but what's doing the else branch? Is it still necessary after changing to prepare_to_wait in -23?

[Łukasz Halman (lukasz-halman)]

I have exactly the same problem. Kernel the 2.6.15-23 kernel freezes when irda-utils are being started. I don't even plug my irda dongle, just starting irda-utils is enough.

Kernel trace is exactly the same as attached in one of above comments.

[Jan Schmidt (thaytan)]

I dist-upgraded yesterday, and was also suffering the same problem, with the same kernel panic trace.

I ended up removing irda-utils to fix it.

[Olivier Cortès (olive)]

Probably not related to the problem, but connected somewhere : I've got no kIrDAd running on my system... I've tried to sync my WorkPad c505 (rebranded Palm m505c) to my IBM X31 using IrDA, and i couldn't. here's what I found in my dmesg :

[Olivier Cortès (olive)]

Note that for me the machine doesn't hang/freeze at all. I was following http://howto.pilot-link.org/irdasync/, but i didn't get much farther when I noticed kIrDAd has died...
I did :
modprobe irda
modprobe ircomm
modprobe ircomm-tty
irattach /dev/ttyS1 -s
cd /dev
mknod ircomm0 c 161 0
irdadump

the dump outputed absolutely nothing, so I went to dmesg, and found the ooops. I don't know what to do next, but if you need more info, feel free to ask.
PS: dapper "up-to-date", kernel 2.6.15-23.39 *686*.

[Marc Schiffbauer (mschiff)]

Hi,

just wanted to confirm that bug: Also happens with that kernel on my Fujitsu-Siemens Lifebook. -22 is working...

-Marc

[Karol Bryd (karolbe)]

the same happens on HP Compaq NC8000...

[robepisc (robepisc)]

Can confirm also on my SiS630 based Gericom laptop.

Today I updated my Breezy laptop to Dapper and, surprise! It locks hard on reboot, just while GDM is loading.

I rebooted in single user mode and discovered the presence of an irda related OOPS in my dmesg log.
That OOPS doesn't seem to have any effect at first, but when irda-utils is initialized (by "/etc/rc2.d/S20irda-utils", which happens to run while GDM is loading), the kernel freezes.

[John Cooper (choffee)]

Happens just like this on my Thinkpad R51 is there any more info that I can provide to help fix this?

Thanks

john

[degerrit (degerrit)]

Any progress on this? Needless to say, I have the same problem (external Tekram IrMate IR-210B serial dongle).

The kernels before the final kernel did NOT have this behaviour: irda worked just fine.

[Ben Collins (ben-collins)]

Fixed the kernel thread's use of wait.

[saquetf (saquetf)]

Hello,

I use ubuntu with linux-image-2.6.15-23-k7 and I have an AMD Athlon k7 with an irda device I made on the motherboard (in BIOS irda replace ttyS1(com2:)). It used to work with previous linux distribs (SuSE, Mandrake) and under Windows.
With Ubuntu 6.06 it doesn't work anymore.
When I start "irdattach /dev/ttyS1 -s" (I use SIR mode with irtty module) then few seconds after that my PC freezes.
Last message is:
irlap_change_speed(), setting speed to 9600

Anybody could help me?

Thanks
Luca

[saquetf (saquetf)]

Hi,

Just update your kernel from linux-image-2.6.15-23 to linux-image-2.6.15-25 and the problem will be fixed :-)

Thanks a lot for this update!
Luca

[degerrit (degerrit)]

Confirmed, IRDA works again.
Thank you Ben!

Adiu,

Veiqui la solucion a ton problema d'IRDA.

$ sudo su
# apt-get update && apt-get upgrade && apt-get dist-upgrade

quo deuria far l'afar. si quo marcha, podeis tornar botar IRDA au
desmaratge emb :

$ sudo sysv-rc-conf

no output from irdadump

I used the following to make usb-irda dongle ma620 work:
#modprobe uhci_hcd
#modprobe pl2303
#modprobe irda
#echo 9600 > /proc/sys/net/irda/max_baud_rate
#modprobe irtty-sir
#modprobe ma600-sir
#modprobe ircomm-tty
#irattach irda0 -d ma600 -s

as there was no output, I used
#irattach /dev/ttyUSB0 -d ma600 -s

I do not have any output with
#irdadump
but dmesg shows:
[4295979.536000] sirdev_receive - too early: e67c4324 / 1!
hundreds of times

[Thierry Blanc (thierry-blanc)]

#modprobe uhci_hcd
#modprobe pl2303
#modprobe irda
#echo 9600 > /proc/sys/net/irda/max_baud_rate
#modprobe irtty-sir
#modprobe ma600-sir
#modprobe ircomm-tty
#irattach /dev/ttyUSB0 -d ma600 -s

dongle works!
