Mark,

Do you have SOL on the HP DL145-G2 ?

I also have these nodes, and although I can use most ipmi functions
(including remote access power up/cycle), I can not get SOL to work.

Also, i have noticed that the kipmi0 daemon does consume a little bit,
e.g., 45 minutes for 9 days uptime (with the top default refresh, it shows
up every 4 screens or so). (CentOS 5.3)

Regards,

paulo
