[Voyage-linux] modprobe scx200_acb : probe failed

[Joe Pulver]

Hello guys,

I'm getting an error ( : probe failed ) when I try to modprobe 
scx200_acb. Despite the error, I'm still able to load the lm77  module, 
and get temperature readings from /sys/bus/i2c/drivers/lm77/....
Since I have a work around, this issue isn't pressing, but I still have 
a two questions about the reported error.

1.  Is it safe to ignore the ' : probe failed ' error message?  Here's a 
quick output of the commands I ran on a new Voyage install.  Any 
thoughts as to what could be causing this?  I have 3 WRAP Boards, which 
all behave the same, so I'm assuming the issue is software.

*************************************

On a second compact flash, I upgraded the Linux Kernel to 2.6.14.  I 
can't remember exactly how, possibly by using apt-get upgrade.  The only 
thing I'm sure about, is that I did not build the Kernel, I just 
installed it.   On a third compact flash, I followed Beats instructions 
in the post on Nov 15. Installing docu for kernel, new madwifi, to build 
a madwifi-ng compatible version of Voyage.

In both cases listed above, the lm77  module eventually loads 
successfully, but again I get errors along the way.  The output from one 
of the cases is below, as both cases are identical.  I get the same 
error on modprobe scx200_acb, this time I can't load i2c-sensor, and 
worst off all, the modprobe lm77 takes ~15 seconds.  I'd like to do this 
stuff on boot, by putting the modules into /etc/modules/ but I can't if 
it's going to add 15 seconds to the boot time. 

Question 2, how do I do away with the 15 second lag time I get when 
trying to load lm77 on newer voyage builds?   Below is the output from 
one of the boards.  I've also tried skipping the 'modprobe i2c-sensor' 
step, but the 15 second delay  is still there.  I've also tried "apt-get 
install lm-sensors" and that didn't get rid of the 15 second delay.

Again, my goal was to get the temp, and that is working, so this issue 
isn't a show stopper for me, I'm just curious as to what is going on, 
and I'd really like the lm77 module to load without a 15 second delay if 
possible.  Any help would be appreciated. 

Joe
