Public bug reported:
Binary package hint: irda-utils
I have an ASUS A3Ac notebook with integrated IrDA. I have been using OpenSuSE
10.2 with 2.6.18.8 and then 2.6.21-rc7-43 kernel. IrDA under OpenSuSE worked
out of the box.
Unfortunately, I am not able to get it working with Kubuntu 7.04 kernel
2.6.20-15.
In fact the IrDA works PERFECTLY when I run the SYSTEM FROM THE CD. It
even works after the system is FRESHLY INSTALLED on the hard drive. But
as soon as the computer is rebooted it never works again !!!!
All the modules needed for running the IrDA are loaded as reported by "lsmod |
grep ir"
ircomm_tty 39560 0
ircomm 23684 1 ircomm_tty
irtty_sir 9600 0
sir_dev 17156 1 irtty_sir
irda 201276 4 ircomm_tty,ircomm,irtty_sir,sir_dev
crc_ccitt 3072 1 irda
But when I try "irattach /dev/ttSy1 -s" i get and check "tail
/var/log/messages" I get following:
Apr 27 00:06:13 A3Ac irattach: Stopping device /dev/ttyS1
Apr 27 00:06:13 A3Ac irattach: ioctl(SIOCGIFFLAGS): No such device
Apr 27 00:06:13 A3Ac irattach: exiting ...
Apr 27 00:06:13 A3Ac kernel: [ 8473.668000] ttyS1: LSR safety check engaged!
In OpenSuSE the IrDA hardware gets attached and I can see that irattach is a
running process and irdadump lists the activity. This is not true in my Kubuntu
system. irattach is not loaded as can be seen from applying the following
command "ps -e | grep ir" which produces:
3 ? 00:00:00 ksoftirqd/0
3589 ? 00:00:00 irda_sir_wq
6295 ? 00:00:15 firefox-bin
obviously when I try "irdadump" I don't get any response.
There is one more interesting aspect to it. I can do irattach /dev/ttSy0 -s and
attach the COM port. I even get output from irdadump, It's just useless because
it's not the correct port.
"dmesg | grep tty" gives following:
