asterisk users - Sep 2009 - chan_dahdi.so fails to load : Inappropriate ioctl for device

Aloha,

I'm not sure why I'm getting this error, but I can't seem to get
chan_dahdi to load. SIP & IAX2 are working fine.

Debian 4 w/ 2.6.28 kernel. Asterisk 1.6.1.5, dahdi-linux 2.2.0.2,
dahdi-tools-2.2.0

CLI> module load chan_dahdi.so
Unable to load module chan_dahdi.so
Command 'module load chan_dahdi.so' failed.

Note, I have compiled DAHDI 2.2.0.2 but it still shows 2.1.0.4 in the
tool. Version bug? If it should say 2.2.0.2, then that could be my
problem. But how do I correct that?

# dahdi_cfg -vvv
DAHDI Tools Version - 2.2.0

DAHDI Version: 2.1.0.4
Echo Canceller(s):
Configuration
=====================

Channel map:

Channel 01: FXS Kewlstart (Default) (Echo Canceler: none) (Slaves: 01)
Channel 02: FXS Kewlstart (Default) (Echo Canceler: none) (Slaves: 02)
Channel 03: FXO Kewlstart (Default) (Echo Canceler: none) (Slaves: 03)
Channel 04: FXO Kewlstart (Default) (Echo Canceler: none) (Slaves: 04)

4 channels to configure.

Setting echocan for channel 1 to none
Setting echocan for channel 2 to none
Setting echocan for channel 3 to none
Setting echocan for channel 4 to none

I have looked up everything I can about this problem, and nothing has lead
me to a solution. Any help would be great appreciated.

Thanks,
Herb

Forgot to include this info in my first post.

# cat /proc/dahdi/*
Span 1: WCTDM/0 "Wildcard AEX410 Board 1" (MASTER)
	IRQ misses: 1

	   1 WCTDM/0/0 FXSKS RED
	   2 WCTDM/0/1 FXSKS RED
	   3 WCTDM/0/2 FXOKS
	   4 WCTDM/0/3 FXOKS

I don't have the analog lines attached to the card yet, hence the RED
alarms.

Span 2: DAHDI_DUMMY/1 "DAHDI_DUMMY/1 (source: HRtimer) 1"

Thanks,
Herb

I think you are correct and that this is your problem.  If you have 
dahdi-tools 2.2.0 installed, but using and older version of dahdi-linux, 
you will get these errors since the format of some of the ioctls have 
changed. (related to https://issues.asterisk.org/view.php?id=14499)

How did you install dahdi-linux?
