Lirc (lirc_dev) causing a Bad EIP on lircd stop

[<li...@jc...>]

Running Mandriva 2007 (2.6.17-5mdv #1 SMP kernel) with 
lirc-0.8.1-0.20060722.4.2mdv2007.0.i586.rpm installed, I'm having persistant 
Bad EIP errors when lircd terminates (normally on system shutdown or reboot). 
Compiling from the 0.8.1 (nonCVS) source did not improve matters. The 
hardware using lirc is a Hauppauge WinTV bt878 card with Hauppauge remote. 

Here's the relevant material from /var/log/messages:

A saa7130 based tv card is also installed, and may be related to the problem. 
This card does not have a remote, but the saa7134 module requires that the 
ir_kbd_i2c module be loaded (this was not the case under Mandriva 2006, where 
this hardware setup worked without any such problems). 

When these modules are present, lirc behaves oddly (when testing with irw I 
frequently receive digits interspersed with the normal irw button-press 
output). These extra signals seem to interfere with the operation of lircd, 
and they definitely interfere with the use of lircmd. I can fix this problem 
by running "rmmod saa7134 ; rmmod ir_kbd_i2c" (although it's hardly ideal as 
it disables the saa7130 card). Removing these modules does not help with the 
Bad EIP error, however.

So, at this point, I'd welcome all recommendations. First and foremost, how to 
run lirc without this problem. I appreciate your time. Thanks in advance for 
the help!
