"lirc_serial: ignoring spike: 1 1 4972e675 4972e675 c26f7 c26cd" problems with serial homebrew

[Miika R. <mra...@gm...>]

Hi,

I upgraded my htpc and now I'm having problems with
serial receiver.

When I try to use remote i get messages to dmesg like

lirc_serial: ignoring spike: 1 1 4972e675 4972e675 c26f7 c26cd
lirc_serial: ignoring spike: 1 1 4972e676 4972e676 c9f5f c9ab6
lirc_serial: ignoring spike: 1 1 4972e67a 4972e67a 13c6f 1394b
lirc_serial: ignoring spike: 1 1 4972e6d0 4972e6d0 8a902 8a454
lirc_serial: ignoring spike: 1 1 4972ef07 4972ed18 6bf10 70c71

and remote is impossible to use. I'm using motherboards serial port. Any 
suggestions for fix or workaround?

Hardware setup:
Asus M3N78-VM
1 sata hdd
1 pata hdd, pata dvd (udma enabled for both)
REALmagic Hollywood Plus DVD Decoder
Philips Semiconductors SAA7146 DVB-C card

Software:
Centos 5.2 with vanilla kernel 2.6.28 SMP
lircd 0.8.4a (I also tried cvs version without luck)
