Hi Cédric, I can confirm that this patchset fixes starting up OpenBIOS for both g3beige/mac99 in my tests here. With the escc fix also applied, the only outstanding issue is the removal of the tlb_flush() statements which causes Darwin, MacOS X and HelenOS 0.60 to panic on boot My only request is if it would be possible to move patch 2 "ppc: Better figure out if processor has HV mode" to the front of this patchset which will make the remaining patches bisectable for the Mac machines. With that: Tested-by: Mark Cave-Ayland <mark.cave-ayl...@ilande.co.uk> Does anyone know if Ben has any ideas as to why the MMU tlb_flush changes patch is causing such problems? ATB, Mark.
