lircd enters "uninterruptible sleep" (Ds)

[Eric Bus-3]

Hi,

I'm having a problem with my current installation of lirc from CVS. I'm
using the lirc_imon driver and kernel 2.6.25.6 (SMP).

When I start irw, everything works OK. I can kill irw, and restart it,
no problem. But when I do the same with mplayer or xine, my lircd enters
the "uninterruptible sleep" state:

3847 ?        Ds     0:00 \/usr/sbin/lircd --driver=default
--device=/dev/lirc0

The only way to 'kill' the process is to do a reboot. I've also tried to
start the daemon with the 'no daemon' (-n) option, but this results in a
'hanging' console.

I've never had this problem with my previous installation, but I
reinstalled my machine and now I'm facing this problem.

I attached a small log file from running $ strace -fvip on the pid and
then calling mplayer. It hangs on the "close(7" call, but I don't know
why. Any ideas? If someone needs more debugging info, please let me know.

I switched back to kernel 2.6.24 SMP (2.6.24-etchnhalf.1-686) and now it
works. I seems like something in 2.6.25 and 2.6.26 is breaking my lirc
support, but I don't know what.

Hi all,
 
I'm looking for a nice simple way to test my d11-100 usb port and have not found way thus far.  I've been fighing with the directv.pl script for over a week now and am starting to believe the DTV support people that say that this port is disabled despite all of the success stories I see on the internet regarding this configuration.  Therefore if you have a way of testing this port I would surely like to hear it.  Any help is appreciated.
 
 
PS. There errors I get are "excesive retries" with /dev/ttyUSB0 as my port.
 
Thanks,
R.

Mine has worked great for me.  I have had the following work for over a year with no problems:

mythbe1 serial port -> Null Modem (I wired this myself rather then buying one) -> IOGear Serial to USB -> DirectTV D11 Tuner

or

mythbe1 USB port -> IOGear Serial to USB -> Null Modem (I wired this myself rather then buying one) -> IOGear Serial to USB -> DirectTV D11 Tuner

Mine did not work at all until I got the null modem wiring working right.
