Re: [BISECTED] SOLVED ipmi_si not loading since 2.6.39

From: Nikola Ciprich

Hi guys,

thanks for all Your help. Problem solved, I have to be very sorry about that :(
There was a boot script I wasn't aware of which we're using for setting IPMI and this
tried to load the module using
modprobe ipmi_si type=kcs ports=0xca8 regspacings=4
THIS seems to have stopped working, but I think it was just wrong all the time, and is
now not needed at all. Just loading ipmi_si now works, so the system was maybe just
getting confused when trying to load module with wrong params (I was unloading module
first, but seems like that wasn't enough).
So I'll just have this script fixed (or better removed).
I'm once again sorry for the fuss, I don't know much about how IPMI works and apparently
haven't gathered all the needed info.

Cheers!

nik
