Since 2.6= =2E39 module loading ends with following message: ipmi_si: Interface detection failed Then ipmitool is unable to control IPMI device.=20 Works for 2.6.38, doesn't work for 2.6.39, 3.0.28, 3.4-rc1. I got this bisected to following commit: commit a1e9c9dd3383e6a1a762464ad604b1081774dbda Author: Rob Herring Date: Wed Feb 23 15:37:59 2011 -0600 ipmi: convert OF driver to platform driver =20 of_bus is deprecated in favor of the plain platform bus. This patch merges the ipmi OF driver with the existing platform driver. =20 CONFIG_PPC_OF occurrances are removed or replaced with CONFIG_OF. =20 Compile tested with and without CONFIG_OF. Tested OF probe and default probe cases. =20 Signed-off-by: Rob Herring Signed-off-by: Grant Likely I wonder whether this is a bug, or I'm doing something wrong?
