OK, thanks for the "tip".

I don't think I'm using anymore the ipmi kernel modules:

% lsmod |grep -i ipmi
[no output]

Sorry: I've tried to use IPMI first (before) omreport, but I was hard 
(I'm newbie about it).
It has worked a few minutes (about 2hour with a request every 30s) ;I 
was able to retrieve temperature from probes, then the kernel complains 
about IPMI and I was bot able anymore to retrieve temp. with command 
"/usr/bin/ipmitool -I open sdr list full"

% grep -i ipmi /var/log/messsages.10
brutus kernel: IPMI message handler: BMC returned incorrect response, 
expected netfn b cmd 23, got netfn b cmd 40
[...]

After reboots (rmmod command on ipmi* modules was unsucesfull), the same 
things happened, so I've decides to avoid IPMI (that is too complicated 
for the simple things I need).

Regards,

Pierre Bourgin
