[lm-sensors] IPMI and ipmisensors on an Intel SC450NX

Tue Oct 2 00:02:21 CEST 2007

Your driver can't be loaded for some reason, and it should be pre-built
in 2.6.21, so that's odd.  Does the /var/log/messages say that it didn't
get a response, or something else?

Another option is to try the user-space KCS code in ipmiutil.
See http://ipmiutil.sf.net, and try 
  ipmiutil health -x
That should show some debug to see if there is any response at 0xca2 at
all.

Unfortunately, neither of this works. I've tried 

root at buick:~# modprobe ipmi_si
FATAL: Error inserting ipmi_si
(/lib/modules/2.6.21/kernel/drivers/char/ipmi/ipmi_si.ko): No such
device
root at buick:~# modprobe ipmi_si type="kcs" ports="0xca0"
FATAL: Error inserting ipmi_si
(/lib/modules/2.6.21/kernel/drivers/char/ipmi/ipmi_si.ko): No such
device
root at buick:~# modprobe ipmi_si type="kcs" ports="0xca2"
FATAL: Error inserting ipmi_si
(/lib/modules/2.6.21/kernel/drivers/char/ipmi/ipmi_si.ko): No such
device

I don't really know if there is more to try. But as you say, the board
should support IPMI, so I don't really know why it doesn't seem to.
Hmm. 

I guess it was worth a try :)

Thanks to everyone who replied :)
