It's not happy on mambo:

WARNING: 20856759: (20856757): Invalid address 0x0000000028096258 in XSCOM range,  SCOM=0x00280962b

FATAL ERROR: 20856759: (20856757): Check Stop for 0:0: Machine Check with ME bit of MSR off

Which looks to be one of the xscom_write()'s from opal_nmmu_set_ptcr().

Do I need a newer mambo?
