Xserve IPMI issue

Sergio David Rodrigues


ipmi_si has an issue on the Xserve 2,1

IPMI: BT reset (takes 5 secs)
IPMI BT: timeout in XACTION [     B_BUSY H2B ]

After spending sometime trying to get it to work i found a solution

Just add ipmi_si.addrs=0x90841000 ipmi_si.irqs=16 to the kernel boot options

In Ubuntu add this to /etc/default/grub

GRUB_CMDLINE_LINUX="ipmi_si.addrs=0x90841000 ipmi_si.irqs=16"

"The si_type may be either "kcs", "smic", or "bt".  If you leave it blank,

it defaults to "kcs"." source: http://openipmi.sourceforge.net/IPMI.txt

According to that, only one can be used!

What happens is kcs loads then bt loads after and then it hangs, adding the mem address and irqs solves this!
