lirc_serial+Tekram IRMate 210B @ my P4 machine fails to work

[Pavel K. <pk...@pi...>]

Hi All

I have a Pentium 4 3Ghz machine with HT on (thus SMP compiled in) and 
running linux kernel 2.6.14. To the ttyS0, the only COM-port, attached 
is an IRDA dongle, Tekram IRMate-210B.

The latest lirc (0.8.0) compiles ok, the lirc_dev module loads without 
problems. However, when I try to insmod lirc-serial, I obtain the 
following messages in the syslog:

BUG: using smp_processor_id() in preemptible [00000001] code: modprobe/30463

lirc_serial: auto-detected active high receiver
lirc_dev: lirc_register_plugin: sample_rate: 0

The module still shows as loaded in the lsmod output, although I fail to 
get any signals with irrecord or mode2.

How is it possible to overcome this bug?

Thanks
