Boot -fails with messages like: - - Could not allocate memory for RTAS -or - No memory for flatten_device_tree (no room) - -Increasing the minimum RMA size to 512MB fixes the problem. This -should not have an impact on smaller LPARs (with 256MB memory), -as the firmware will cap the RMA to the memory assigned to the LPAR. - -Fix is based on input/discussions with Michael Ellerman. Thanks to -Praveen K. Pandey for testing on a large system. - -Reported-by: Praveen K.
